Hi all, This patchset implements an online checker for the realtime summary file. We begin with the xfile code from the repair series, which we use here to build an in-memory copy of the summary information from the ondisk realtime bitmap that can be paged out to disk. Next, we move the rtsummary scrubber stub function into a separate file. The final patch in the series implements the logic to build the rtsummary file and compare it to the existing contents. 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=scrub-rtsummary --- fs/xfs/Kconfig | 1 fs/xfs/Makefile | 8 - fs/xfs/scrub/array.c | 665 ++++++++++++++++++++++++++++++++++++++++++++++ fs/xfs/scrub/array.h | 49 +++ fs/xfs/scrub/common.h | 10 + fs/xfs/scrub/rtbitmap.c | 41 --- fs/xfs/scrub/rtsummary.c | 327 +++++++++++++++++++++++ fs/xfs/scrub/scrub.c | 9 - fs/xfs/scrub/scrub.h | 7 fs/xfs/scrub/trace.c | 1 fs/xfs/scrub/trace.h | 118 ++++++++ fs/xfs/scrub/xfile.c | 271 +++++++++++++++++++ fs/xfs/scrub/xfile.h | 23 ++ 13 files changed, 1486 insertions(+), 44 deletions(-) create mode 100644 fs/xfs/scrub/array.c create mode 100644 fs/xfs/scrub/array.h create mode 100644 fs/xfs/scrub/rtsummary.c create mode 100644 fs/xfs/scrub/xfile.c create mode 100644 fs/xfs/scrub/xfile.h
