This is the v2 userspace portion of finobt support corresponding to v2
of the kernel series.
Patches 1-10 are straight application of the corresponding kernel patches
with omissions where appropriate. At this point, I'd suggest review of
those patches target the kernel equivalents, as this set will progress
using the kernel set as a base.
Patch 11 adds mkfs support. Patches 12 and 13 provide a couple minor db
and repair fixes to support the new agi fields and calculate the fs
format respectively. Patches 14-18 add real repair support for the
finobt. Patch 19 adds support to report finobt state in xfs_info. Patch
20 adds support for metadump.
Note that this series is based on Dave's latest (v5) CRC write support
series for userspace:
This is required for metadump support in particular.
I think this set is now fairly comprehensive in terms of finobt support.
My biggest question at the moment is with regard to how far to enhance
repair support. Repair currently scans the finobt in phase 2, attempts
to call out inconsistencies and regenerates the finobt based on the
in-core data in phase 5. Once basic support is ironed out, we have a
duplicate source of a subset of inode metadata (chunks with free inodes)
from which to potentially make more intelligent repair decisions.
- Rebased onto the CRC v5 series and v2 kernel finobt bits.
- Core finobt repair support.
- xfs_info support.
- xfs_metadump support.
