The new DIO bio splitting code has problems when the bio
spans more than one ordered extent. This will happen as the
generic DIO code merges our get_blocks calls together into
a bigger single bio.
This fixes things by walking forward in the ordered extent
code finding all the overlapping ordered extents and completing them
all at once.

And in particular, use it in 'pipe_fcntl()'.
The other pipe functions do not need to use the 'careful' version, since
they are only ever called for things that are already known to be pipes.
The normal read/write/ioctl functions are called through the file
operations structures, so if a file isn't a pipe, they'd never get
called. But pipe_fcntl() is special, and called directly from the
generic fcntl code, and needs to use the same careful function that the
splice code is using.

.. and change it to take the 'file' pointer instead of an inode, since
that's what all users want anyway.
The renaming is preparatory to exporting it to other users. The old
'pipe_info()' name was too generic and is already used elsewhere, so
before making the function public we need to use a more specific name.

There is a problem with how we use sget, it searches through the list of supers
attached to the fs_type looking for a super with the same fs_devices as what
we're trying to mount. This depends on sb->s_fs_info being filled, but we don't
fill that in until we get to btrfs_fill_super, so we could hit supers on the
fs_type super list that have a null s_fs_info. In order to fix that we need to
go ahead and setup a blank root with a blank fs_info to hold fs_devices, that
way our test will work out right and then we can set s_fs_info in
btrfs_set_super, and then open_ctree will simply use our pre-allocated root and
fs_info when setting everything up. Thanks,

There are two big problems currently with FIEMAP
1) We return extents for holes. This isn't supposed to happen, we just don't
return extents for holes and then userspace interprets the lack of an extent as
a hole.
2) We sometimes don't set FIEMAP_EXTENT_LAST properly. This is because we wait
to see a EXTENT_FLAG_VACANCY flag on the em, but this won't happen if say we ask
fiemap to map up to the last extent in a file, and there is nothing but holes up
to the i_size. To fix this we need to lookup the last extent in this file and
save the logical offset, so if we happen to try and map that extent we can be
sure to set FIEMAP_EXTENT_LAST.
With this patch we now pass xfstest 225, which we never have before.

When mounting a btrfs file system btrfs_test_super() may attempt to
use sb->s_fs_info, the btrfs root, of a super block that is going away
and that has had the btrfs root set to NULL in its ->put_super(). But
if the super block is going away it cannot be an existing super block
so we can return false in this case.

There is a typo in __btrfs_prealloc_file_range() where we set the i_size to
actual_len/cur_offset, and then just set it to cur_offset again, and do the same
with btrfs_ordered_update_i_size(). This fixes it back to keeping i_size in a
local variable and then updating i_size properly. Tested this with
xfs_io -F -f -c "falloc 0 1" -c "pwrite 0 1" foo
stat'ing foo gives us a size of 1 instead of 4096 like it was. Thanks,

reiserfs_unpack() locks the inode mutex with reiserfs_mutex_lock_safe()
to protect against reiserfs lock dependency. However this protection
requires to have the reiserfs lock to be locked.
This is the case if reiserfs_unpack() is called by reiserfs_ioctl but
not from reiserfs_quota_on() when it tries to unpack tails of quota
files.
Fix the ordering of the two locks in reiserfs_unpack() to fix this
issue.

Currently one pagemap_read() call walks in PAGEMAP_WALK_SIZE bytes (== 512
pages.) But there is a corner case where walk_pmd_range() accidentally
runs over a VMA associated with a hugetlbfs file.
For example, when a process has mappings to VMAs as shown below:
# cat /proc/<pid>/maps
...
3a58f6d000-3a58f72000 rw-p 00000000 00:00 0
7fbd51853000-7fbd51855000 rw-p 00000000 00:00 0
7fbd5186c000-7fbd5186e000 rw-p 00000000 00:00 0
7fbd51a00000-7fbd51c00000 rw-s 00000000 00:12 8614 /hugepages/test
then pagemap_read() goes into walk_pmd_range() path and walks in the range
0x7fbd51853000-0x7fbd51a53000, but the hugetlbfs VMA should be handled by
walk_hugetlb_range(). Otherwise PMD for the hugepage is considered bad
and cleared, which causes undesirable results.
This patch fixes it by separating pagemap walk range into one PMD.

The attribute cache for a file was not being cleared when a file is opened
with O_TRUNC.
If the filesystem's open operation truncates the file ("atomic_o_trunc"
feature flag is set) then the kernel should invalidate the cached st_mtime
and st_ctime attributes.
Also i_size should be explicitly be set to zero as it is used sometimes
without refreshing the cache.

Everybody who calls btrfs_add_nondir just passes in the dentry of the new file
and then dereference dentry->d_parent->d_inode, but everybody who calls
btrfs_add_nondir() are already passed the parent's inode. So instead of
dereferencing dentry->d_parent, just make btrfs_add_nondir take the dir inode as
an argument and pass that along so we don't have to worry about d_parent.

Since we walk up the path logging all of the parts of the inode's path, we need
to hold i_mutex to make sure that the inode is not renamed while we're logging
everything. btrfs_log_dentry_safe does dget_parent and all of that jazz, but we
may get unexpected results if the rename changes the inode's location while
we're higher up the path logging those dentries, so do this for safety reasons.

There are lots of places where we do dentry->d_parent->d_inode without holding
the dentry->d_lock. This could cause problems with rename. So instead we need
to use dget_parent() and hold the reference to the parent as long as we are
going to use it's inode and then dput it at the end.

When creating new inodes we don't setup inode->i_generation. So if we generate
an fh with a newly created inode we save the generation of 0, but if we flush
the inode to disk and have to read it back when getting the inode on the server
we'll have the right i_generation, so gens wont match and we get ESTALE. This
patch properly sets inode->i_generation when we create the new inode and now I'm
no longer getting ESTALE. Thanks,

People kept reporting NFS issues, specifically getting ESTALE alot. I figured
out how to reproduce the problem
SERVER
mkfs.btrfs /dev/sda1
mount /dev/sda1 /mnt/btrfs-test
<add /mnt/btrfs-test to /etc/exports>
btrfs subvol create /mnt/btrfs-test/foo
service nfs start
CLIENT
mount server:/mnt/btrfs /mnt/test
cd /mnt/test/foo
ls
SERVER
echo 3 > /proc/sys/vm/drop_caches
CLIENT
ls <-- get an ESTALE here
This is because the standard way to lookup a name in nfsd is to use readdir, and
what it does is do a readdir on the parent directory looking for the inode of
the child. So in this case the parent being / and the child being foo. Well
subvols all have the same inode number, so doing a readdir of / looking for
inode 256 will return '.', which obviously doesn't match foo. So instead we
need to have our own .get_name so that we can find the right name.
Our .get_name will either lookup the inode backref or the root backref,
whichever we're looking for, and return the name we find. Running the above
reproducer with this patch results in everything acting the way its supposed to.

Migrate page will directly call the btrfs btree writepage function,
which isn't actually allowed.
Our writepage assumes that you have locked the extent_buffer and
flagged the block as written. Without doing these steps, we can

it is really only safely used internally by btrfs. We

Filesystem independent ioctl was rejected as not common enough to be in
core vfs ioctl. Since we still need to access to this functionality this
commit adds ext4 specific ioctl EXT4_IOC_TRIM to dispatch
ext4_trim_fs().
It takes fstrim_range structure as an argument. fstrim_range is definec in
the include/linux/fs.h and its definition is as follows.
struct fstrim_range {
__u64 start;
__u64 len;
__u64 minlen;
}
start - first Byte to trim
len - number of Bytes to trim from start
minlen - minimum extent length to trim, free extents shorter than this
number of Bytes will be ignored. This will be rounded up to fs
block size.
After the FITRIM is done, the number of actually discarded Bytes is stored
in fstrim_range.len to give the user better insight on how much storage
space has been really released for wear-leveling.
