xfs: make iomap_begin functions trim iomaps consistently Historically, the XFS iomap_begin function only returned mappings for exactly the range queried, i.e. it doesn't do XFS_BMAPI_ENTIRE lookups. The current vfs iomap consumers are only set up to deal with trimmed mappings. xfs_xattr_iomap_begin does BMAPI_ENTIRE lookups, which is inconsistent with the current iomap usage. Remove the flag so that both iomap_begin functions behave the same way. FWIW this also fixes a behavioral regression in xattr FIEMAP that was introduced in 4.8 wherein attr fork extents are no longer trimmed like they used to be. Signed-off-by: Darrick J.
