Subject: [PATCH 0/2] xfs: fallocate RT flush unmap range fixes
Date: Thu, 9 May 2024 10:40:55 +0000 [thread overview]
Message-ID: <20240509104057.1197846-1-john.g.garry@oracle.com> (raw)
As mentioned by Dave Chinner at [0], xfs_flush_unmap_range() and
xfs_prepare_shift() should consider RT extents in the flush unmap range,
and need to be fixed.
I don't want to add such changes to that series, so I am sending
separately.
About the change in xfs_prepare_shift(), that function is only called
from xfs_insert_file_space() and xfs_collapse_file_space(). Those
functions only permit RT extent-aligned calls in xfs_is_falloc_aligned(),
so in practice I don't think that this change would affect
xfs_prepare_shift(). And xfs_prepare_shift() calls
xfs_flush_unmap_range(), which is being fixed up anyway.

Changes since RFC:
- Use roundup() and rounddown() (Darrick)
- Change xfs_prepare_shift() comment (Darrick)
- Add Christoph's RB tags - I think ok, even though code has changed
since RFC

xfs: Fix xfs_flush_unmap_range() range for RT
