Subject: xfs: BMAPX shouldn't barf on inline-format directories
From: Darrick J. Wong <[email protected]>
commit 6eadbf4c8ba816c10d1c97bed9aa861d9fd17809 upstream.
When we're fulfilling a BMAPX request, jump out early if the data fork is in local format. This prevents us from hitting a debugging check in bmapi_read and barfing errors back to userspace. The on-disk extent count check later isn't sufficient for IF_DELALLOC mode because da extents are in memory and not on disk.
