2009-10-30xfs: free temporary cursor in xfs_diallocEric Sandeen
Commit bd169565993b39b9b4b102cdac8b13e0a259ce2f seems to have a slight regression where this code path: if (!--searchdistance) { /* * Not in range - save last search * location and allocate a new inode */ ... goto newino; } doesn't free the temporary cursor (tcur) that got dup'd in this function. This leaks an item in the xfs_btree_cur zone, and it's caught on module unload: =========================================================== BUG xfs_btree_cur: Objects remaining on kmem_cache_close() ----------------------------------------------------------- It seems like maybe a single free at the end of the function might be cleaner, but for now put a del_cursor right in this code block similar to the handling in the rest of the function.

2009-09-01xfs: rationalize xfs_inobt_lookup*Christoph Hellwig
Currenly we have a xfs_inobt_lookup* variant for each comparism direction, and all these get all three fields of the inobt records passed, while the common case is just looking for the inode number and we have only marginally more callers than xfs_inobt_lookup* variants. So opencode a direct call to xfs_btree_lookup for the single case where we need all fields, and replace xfs_inobt_lookup* with a xfs_inobt_looku that just takes the inode number and the direction for all other callers.

2008-04-29[XFS] Don't initialise new inode generation numbers to zeroDavid Chinner
When we allocation new inode chunks, we initialise the generation numbers to zero. This works fine until we delete a chunk and then reallocate it, resulting in the same inode numbers but with a reset generation count. This can result in inode/generation pairs of different inodes occurring relatively close together. Given that the inode/gen pair makes up the "unique" portion of an NFS filehandle on XFS, this can result in file handles cached on clients being seen on the wire from the server but refer to a different file. This causes .... issues for NFS clients. Hence we need a unique generation number initialisation for each inode to prevent reuse of a small portion of the generation number space. Use a random number to initialise the generation number so we don't need to keep any new state on disk whilst making the new number difficult to guess from previous allocations.

2008-04-18[XFS] Account for inode cluster alignment in all allocationsDavid Chinner
At ENOSPC, we can get a filesystem shutdown due to a cancelling a dirty transaction in xfs_mkdir or xfs_create. This is due to the initial allocation attempt not taking into account inode alignment and hence we can prepare the AGF freelist for allocation when it's not actually possible to do an allocation. This results in inode allocation returning ENOSPC with a dirty transaction, and hence we shut down the filesystem. Because the first allocation is an exact allocation attempt, we must tell the allocator that the alignment does not affect the allocation attempt. i.e. we will accept any extent alignment as long as the extent starts at the block we want. Unfortunately, this means that if the longest free extent is less than the length + alignment necessary for fallback allocation attempts but is long enough to attempt a non-aligned allocation, we will modify the free list. If we then have the exact allocation fail, all other allocation attempts will also fail due to the alignment constraint being taken into account. Hence the initial attempt needs to set the "alignment slop" field so that alignment, while not required, must be taken into account when determining if there is enough space left in the AG to do the allocation. That means if the exact allocation fails, we will not dirty the freelist if there is not enough space available fo a subsequent allocation to succeed. Hence we get an ENOSPC error back to userspace without shutting down the filesystem.

2008-02-28[XFS] If you mount an XFS filesystem with no mount options at all, thenJosef Jeff Sipek
the "ikeep" option is set rather than "noikeep". This regression was introduced in 970451. With no mount options specified, xfs_parseargs() does the following: int ikeep = 0; args->flags |= XFSMNT_BARRIER; args->flags2 |= XFSMNT2_COMPAT_IOSIZE; if (!options) goto done; It only sets the above two options by default and before, it also used to set XFSMNT_IDELETE by default. If options are specified, then if (!(args->flags & XFSMNT_DMAPI) && !ikeep) args->flags |= XFSMNT_IDELETE; is executed later on which is skipped by the "goto done;" above.

2007-07-14[XFS] Lazy Superblock CountersDavid Chinner
When we have a couple of hundred transactions on the fly at once, they all typically modify the on disk superblock in some way. create/unclink/mkdir/rmdir modify inode counts, allocation/freeing modify free block counts. When these counts are modified in a transaction, they must eventually lock the superblock buffer and apply the mods. The buffer then remains locked until the transaction is committed into the incore log buffer. The result of this is that with enough transactions on the fly the incore superblock buffer becomes a bottleneck. The result of contention on the incore superblock buffer is that transaction rates fall - the more pressure that is put on the superblock buffer, the slower things go. The key to removing the contention is to not require the superblock fields in question to be locked. We do that by not marking the superblock dirty in the transaction. IOWs, we modify the incore superblock but do not modify the cached superblock buffer. In short, we do not log superblock modifications to critical fields in the superblock on every transaction. In fact we only do it just before we write the superblock to disk every sync period or just before unmount. This creates an interesting problem - if we don't log or write out the fields in every transaction, then how do the values get recovered after a crash? the answer is simple - we keep enough duplicate, logged information in other structures that we can reconstruct the correct count after log recovery has been performed. It is the AGF and AGI structures that contain the duplicate information; after recovery, we walk every AGI and AGF and sum their individual counters to get the correct value, and we do a transaction into the log to correct them. An optimisation of this is that if we have a clean unmount record, we know the value in the superblock is correct, so we can avoid the summation walk under normal conditions and so mount/recovery times do not change under normal operation. One wrinkle that was discovered during development was that the blocks used in the freespace btrees are never accounted for in the AGF counters. This was once a valid optimisation to make; when the filesystem is full, the free space btrees are empty and consume no space. Hence when it matters, the "accounting" is correct. But that means the when we do the AGF summations, we would not have a correct count and xfs_check would complain. Hence a new counter was added to track the number of blocks used by the free space btrees. This is an *on-disk format change*. As a result of this, lazy superblock counters are a mkfs option and at the moment on linux there is no way to convert an old filesystem. This is possible - xfs_db can be used to twiddle the right bits and then xfs_repair will do the format conversion for you. Similarly, you can convert backwards as well. At some point we'll add functionality to xfs_admin to do the bit twiddling easily....

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
