2009-10-08xfs: implement ->dirty_inode to fix timestamp handlingChristoph Hellwig
This is picking up on Felix's repost of Dave's patch to implement a .dirty_inode method. We really need this notification because the VFS keeps writing directly into the inode structure instead of going through methods to update this state. In addition to the long-known atime issue we now also have a caller in VM code that updates c/mtime that way for shared writeable mmaps. And I found another one that no one has noticed in practice in the FIFO code. So implement ->dirty_inode to set i_update_core whenever the inode gets externally dirtied, and switch the c/mtime handling to the same scheme we already use for atime (always picking up the value from the Linux inode). Note that this patch also removes the xfs_synchronize_atime call in xfs_reclaim it was superflous as we already synchronize the time when writing the inode via the log (xfs_inode_item_format) or the normal buffers (xfs_iflush_int). In addition also remove the I_CLEAR check before copying the Linux timestamps - now that we always have the Linux inode available we can always use the timestamps in it. Also switch to just using file_update_time for regular reads/writes - that will get us all optimization done to it for free and make sure we notice early when it breaks.

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.

2009-09-01xfs: improve xfs_inobt_get_rec prototypeChristoph Hellwig
Most callers of xfs_inobt_get_rec need to fill a xfs_inobt_rec_incore_t, and those who don't yet are fine with a xfs_inobt_rec_incore_t, instead of the three individual variables, too. So just change xfs_inobt_get_rec to write the output into a xfs_inobt_rec_incore_t directly.

2008-12-02[XFS] Fix xfs_bulkstat_one size checks & error handlingsandeen@sandeen.net
The 32-bit xfs_blkstat_one handler was failing because a size check checked whether the remaining (32-bit) user buffer was less than the (64-bit) bulkstat buffer, and failed with ENOMEM if so. Move this check into the respective handlers so that they check the correct sizes. Also, the formatters were returning negative errors or positive bytes copied; this was odd in the positive error value world of xfs, and handled wrong by at least some of the callers, which treated the bytes returned as an error value.

Later both will be replaced with helpers once we get the larger CRC-enabled dinode.

2008-04-18[XFS] Don't block pdflush when writing back inodesDavid Chinner
When pdflush is writing back inodes, it can get stuck on inode cluster buffers that are currently under I/O. This occurs when we write data to multiple inodes in the same inode cluster at the same time. Effectively, delayed allocation marks the inode dirty during the data writeback. Hence if the inode cluster was flushed during the writeback of the first inode, the writeback of the second inode will block waiting for the inode cluster write to complete before writing it again for the newly dirtied inode. Basically, we want to avoid this from happening so we don't block pdflush and slow down all of writeback. Hence we introduce a non-blocking async inode flush flag that pdflush uses. If this flag is set, we use non-blocking operations (e.g. try locks) whereever we can to avoid blocking or extra I/O being issued.

2007-12-10[XFS] 971064 Various fixups for xfs_bulkstat().Lachlan McIlroy
- sanity check for NULL user buffer in xfs_ioc_bulkstat[_compat]() - remove the special case for XFS_IOC_FSBULKSTAT with count == 1. This special case causes bulkstat to fail because the special case uses xfs_bulkstat_single() instead of xfs_bulkstat() and the two functions have different semantics. xfs_bulkstat() will return the next inode after the one supplied while skipping internal inodes (ie quota inodes). xfs_bulkstate_single() will only lookup the inode supplied and return an error if it is an internal inode. - in xfs_bulkstat(), need to initialise 'lastino' to the inode supplied so in cases were we return without examining any inodes the scan wont restart back at zero. - sanity check for valid *ubcountp values. Cannot sanity check for valid ubuffer here because some users of xfs_bulkstat() don't supply a buffer. - checks against 'ubleft' (the space left in the user's buffer) should be against 'statstruct_size' which is the supplied minimum object size. The mixture of checks against statstruct_size and 0 was one of the reasons we were skipping inodes. - if the formatter function returns BULKSTAT_RV_NOTHING and an error and the error is not ENOENT or EINVAL then we need to abort the scan. ENOENT is for inodes that are no longer valid and we just skip them. EINVAL is returned if we try to lookup an internal inode so we skip them too. For a DMF scan if the inode and DMF attribute cannot fit into the space left in the user's buffer it would return ERANGE. We didn't handle this error and skipped the inode. We would continue to skip inodes until one fitted into the user's buffer or we completed the scan. - put back the recalculation of agino (that got removed with the last fix) at the end of the while loop. This is because the code at the start of the loop expects agino to be the last inode examined if it is non-zero. - if we found some inodes but then encountered an error, return success this time and the error next time. If the formatter aborted with ENOMEM we will now return this error but only if we couldn't read any inodes. Previously if we encountered ENOMEM without reading any inodes we returned a zero count and no error which falsely indicated the scan was complete.

2007-10-16[XFS] This fix prevents bulkstat from spinning in an infinite loop.Lachlan McIlroy
Here 'agino' increments through the inodes in an allocation group. At the end of the innermost 'for' loop it will hold the value of the next inode to look at (ie the first inode in the next cluster/chunk). Assigning 'lastino' to 'agino' resets it to the last inode in the last inode cluster we just looked at. This causes us to look up the very same cluster and examine all the inodes all over again, and again, and again... We also want to set 'lastino' for the cases when we're not interested in the inode so that the next call to bulkstat won't re-examine the same uninteresting inodes.

2007-10-16[XFS] get_bulkall() could return incorrect inode stateVlad Apostolov
In the following scenario xfs_bulkstat() returns incorrect stale inode state: 1. File_A is created and its inode synced to disk. 2. File_A is unlinked and doesn't exist anymore. 3. Filesystem sync is invoked. 4. File_B is created. File_B happens to reclaim File_A's inode. 5. xfs_bulkstat() is called and detects File_B but reports the incorrect File_A inode state. Explanation for the incorrect inode state is that inodes are not immediately synced on file create for performance reasons. This leaves the on-disk inode buffer uninitialized (or with old state from a previous generation inode) and this is what xfs_bulkstat() would report. The patch marks the on-disk inode buffer "dirty" on unlink. When the inode is reclaimed (by a new file create), xfs_bulkstat() would filter this inode by the "dirty" mark. Once the inode is flushed to disk, the on-disk buffer "dirty" mark is automatically removed and a following xfs_bulkstat() would return the correct inode state. Marking the on-disk inode buffer "dirty" on unlink is achieved by setting the on-disk di_nlink field to 0. Note that the in-core di_nlink has already been set to 0 and a corresponding transaction logged by xfs_droplink(). This is an exception from the rule that any on-disk inode buffer changes has to be followed by a disk write (inode flush). Synchronizing the in-core to on-disk di_nlink values in advance (before the actual inode flush to disk) should be fine in this case because the inode is already unlinked and it would never change its di_nlink again for this inode generation.
