* [XFS] Always reset btree cursor after an insertLachlan McIlroy2008-07-28
| | | | | | | | | | | | | | | | After a btree insert operation a cursor can be invalid due to block splits and a maybe a new root block. We reset the cursor in xfs_bmbt_insert() in the cases where we think we need to but it isn't enough as we still see assertions. Just do what we do elsewhere and reset the cursor unconditionally. Also remove the fix to revalidate the original cursor in xfs_bmbt_insert().

* [XFS] xfs_bmap_compute_maxlevels should be based on di_forkoffTim Shimmin2008-04-17
| | | | | | | | | | | | | | | | Fix up xfs_bmap_compute_maxlevels() to account for the case when we go from using attr2 to using attr1. In that case attr1 will no longer necessarily be at m_attr_offset>>3, but could be at a different value for di_forkoff. Therefore, we return the worst case scenario using MINDBTPTRS and MINABTPTRS, as this function is used for determining the maximum log space.

* [XFS] Prevent xfs_bmap_check_leaf_extents() referencing unmapped memory.Lachlan McIlroy2008-04-17
| | | | | | | | | | | | | | | | | While investigating the extent corruption bug I ran into this bug in debug only code. xfs_bmap_check_leaf_extents() loops through the leaf blocks of the extent btree checking that every extent is entirely before the next extent. It also compares the last extent in the previous block to the first extent in the current block when the previous block has been released and potentially unmapped. So take a copy of the last extent instead of a pointer. Also move the last extent check out of the loop because we only need to do it once.

* [XFS] optimize XFS_IS_REALTIME_INODE w/o realtime configEric Sandeen2008-02-07
| | | | | | | | | | | | | | | | | | | | | | | | Use XFS_IS_REALTIME_INODE in more places, and #define it to 0 if CONFIG_XFS_RT is off. This should be safe because mount checks in xfs_rtmount_init: so if we get mounted w/o CONFIG_XFS_RT, no realtime inodes should be encountered after that. Defining XFS_IS_REALTIME_INODE to 0 saves a bit of stack space, presumeably gcc can optimize around the various "if (0)" type checks: xfs_alloc_file_space -8 xfs_bmap_adjacent -16 xfs_bmapi -8 xfs_bmap_rtalloc -16 xfs_bunmapi -28 xfs_free_file_space -64 xfs_imap +8 <-- ? hmm. xfs_iomap_write_direct -12 xfs_qm_dqusage_adjust -4 xfs_qm_vop_chown_reserve -4 SGI-PV: 971186 SGI-Modid: xfs-linux-melb:xfs-kern:30014a Signed-off-by: Eric Sandeen <sandeen@sandeen.net> Signed-off-by: David Chinner <dgc@sgi.com> Signed-off-by: Lachlan McIlroy <lachlan@sgi.com>

* [XFS] Concurrent Multi-File Data StreamsDavid Chinner2007-07-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In media spaces, video is often stored in a frame-per-file format. When dealing with uncompressed realtime HD video streams in this format, it is crucial that files do not get fragmented and that multiple files a placed contiguously on disk. When multiple streams are being ingested and played out at the same time, it is critical that the filesystem does not cross the streams and interleave them together as this creates seek and readahead cache miss latency and prevents both ingest and playout from meeting frame rate targets. This patch set creates a "stream of files" concept into the allocator to place all the data from a single stream contiguously on disk so that RAID array readahead can be used effectively. Each additional stream gets placed in different allocation groups within the filesystem, thereby ensuring that we don't cross any streams. When an AG fills up, we select a new AG for the stream that is not in use. The core of the functionality is the stream tracking - each inode that we create in a directory needs to be associated with the directories' stream. Hence every time we create a file, we look up the directories' stream object and associate the new file with that object. Once we have a stream object for a file, we use the AG that the stream object point to for allocations. If we can't allocate in that AG (e.g. it is full) we move the entire stream to another AG. Other inodes in the same stream are moved to the new AG on their next allocation (i.e. lazy update). Stream objects are kept in a cache and hold a reference on the inode. Hence the inode cannot be reclaimed while there is an outstanding stream reference. This means that on unlink we need to remove the stream association and we also need to flush all the associations on certain events that want to reclaim all unreferenced inodes (e.g. filesystem freeze).

* [XFS] Fix to prevent the notorious 'NULL files' problem after a crash.Lachlan McIlroy2007-05-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The problem that has been addressed is that of synchronising updates of the file size with writes that extend a file. Without the fix the update of a file's size, as a result of a write beyond eof, is independent of when the cached data is flushed to disk. Often the file size update would be written to the filesystem log before the data is flushed to disk. When a system crashes between these two events and the filesystem log is replayed on mount the file's size will be set but since the contents never made it to disk the file is full of holes. If some of the cached data was flushed to disk then it may just be a section of the file at the end that has holes. There are existing fixes to help alleviate this problem, particularly in the case where a file has been truncated, that force cached data to be flushed to disk when the file is closed. If the system crashes while the file(s) are still open then this flushing will never occur. The fix that we have implemented is to introduce a second file size, called the in-memory file size, that represents the current file size as viewed by the user. The existing file size, called the on-disk file size, is the one that get's written to the filesystem log and we only update it when it is safe to do so. When we write to a file beyond eof we only update the in- memory file size in the write operation. Later when the I/O operation, that flushes the cached data to disk completes, an I/O completion routine will update the on-disk file size. The on-disk file size will be updated to the maximum offset of the I/O or to the value of the in-memory file size if the I/O includes eof.
