Changes since last update:
- Clean up duplicate includes
- Remove ancient 'no-alloc' crap code that occasionally caused hard fs
shutdowns due to lack of proper space reservations
- Fix regression in FIEMAP behavior when reporting xattr extents
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.
