Hi all, Dave and I were talking about various issues that he had discovered while wandering through the log recovery code, and then I started taking a closer look and found bugs aplenty. This first series is a very short one that cleans up some low hanging fruit I found -- the most serious is that we don't log new intent items created in the process of recovering intent items that we found in the log, which breaks the recoverability of log chains. The other thing I found was that bmap intent recovery didn't attach dquots, which could lead to incorrect quota accounting if the BUI recovery caused a bmap btree shape change. If you're going to start using this mess, you probably ought to just pull from my git trees, which are linked below. This is an extraordinary way to destroy everything. Enjoy! Comments and questions are, as always, welcome. --D kernel git tree: https://git.kernel.org/cgit/linux/kernel/git/djwong/xfs-linux.git/log/?h=fix-log-intent-recovery --- fs/xfs/libxfs/xfs_defer.c | 26 ++++++++++++++++++++++++-- fs/xfs/libxfs/xfs_defer.h | 6 ++++++ fs/xfs/xfs_bmap_item.c | 7 ++++++- fs/xfs/xfs_refcount_item.c | 2 +- 4 files changed, 37 insertions(+), 4 deletions(-)
