2008-09-25Btrfs: optimize btrget/set/removexattrChristoph Hellwig
btrfs actually stores the whole xattr name, including the prefix ondisk, so using the generic resolver that strips off the prefix is not very helpful. Instead do the real ondisk xattrs manually and only use the generic resolver for synthetic xattrs like ACLs.

2008-09-25btrfs: optmize listxattrChristoph Hellwig
The ->list handler is really not useful at all, because we always call btrfs_xattr_generic_list anyway. After this is done find_btrfs_xattr_handler becomes unused, and it becomes obvious that the temporary name buffer allocation isn't needed but we can directly copy into the supplied buffer. Tested with various getfattr -d calls on varying xattr lists. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Chris Mason <chris.mason@oracle.com>
2008-09-25Btrfs: compile when posix acl's are disabledJosef Bacik
This patch makes btrfs so it will compile properly when acls are disabled. I tested this and it worked with CONFIG_FS_POSIX_ACL off and on. Signed-off-by: Chris Mason <chris.mason@oracle.com>

2008-09-25Btrfs: Make ACLs return EOPNOTSUPP for nowJosef Bacik
There was a slight problem with ACL's returning EINVAL when you tried to set an ACL. This isn't correct, we should be returning EOPNOTSUPP, so I did a very ugly thing and just commented everybody out and made them return EOPNOTSUPP. This is only temporary, I'm going back to implement ACL's, but Chris wants to push out a release so this will suffice for now. Also Yan suggested setting reada to -1 in the delete case to enable backwards readahead, and in the listxattr case I moved path->reada = 2; to after the if (!path) check so we can avoid a possible null dereference.
