Hi folks, The inode reclaim patchset has grown somewhat larger with all the fixes I've accrued over the past couple of days for issues that have been reported. I've just re-ordered the patchset to have all the bug fixes that need to go into 4.6-rc up front, followed by other bug fixes, followed by all the cleanups I wrote as I went along fixing things. I want to get this out before LSFMM, so I'm posting this before I've done a full verification that I've got the patches correct, and they are still running through xfstests right now. Patch 1 is new - it fixes a regression introduced in 4.6-rc1 and is caused by clearing the vfs inode i_mode in ->evict_inode, when there is code in evict() that requires the mode to be intact until ->destroy_inode. Patch 2 is new - if fixes the inode log item leak that left a dirty log item on the AIL after the inode had been reclaimed, resulting in unmountable filesystems and a couple of use-after-free vectors. Patch 3 is the original fix for the xfs_iflush_cluster lookup validity checks that were incorect Patch 4 is the original fix for avoiding flushing stale inodes. Patch 5 is new, and comes from Alex @ Zadara to avoid having to reallocate memory when tearing down the inode extent lists. This is a necessary pre-requisite for patch 6. Patch 6 is the original patch that pushed all the inode memory freeing into the RCU callback, so that xfs_iflush_cluster didn't reference freed memory when racing with reclaim. Patch 7 is the original patch that made reclaim races eaasier to detect. Patch 8 is the original patch that drops out of xfs-iflush_cluster on the first inode beyond the end of the current cluster. Patch 9 is the original patch that renames the variables in xfs_iflush_cluster(). Patch 10 and 11 are new patches that simplify the inode reclaim tagging interfaces to remove dependencies on the struct xfs_inode and the inode number where they are not actually required. -Dave. _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
