Merge branch 'iomap-write' into linux-gfs2/for-next
Pull in the gfs2 iomap-write changes: Tweak the existing code to
properly support iomap write and eliminate an unnecessary special case
in gfs2_block_map. Implement iomap write support for buffered and
direct I/O. Simplify some of the existing code and eliminate code that
is no longer used:
gfs2: Remove gfs2_write_{begin,end}
gfs2: iomap direct I/O support
gfs2: gfs2_extent_length cleanup
gfs2: iomap buffered write support
gfs2: Further iomap cleanups
This is based on the following changes on the xfs 'iomap-4.19-merge'
branch:
iomap: add private pointer to struct iomap
iomap: add a page_done callback
iomap: generic inline data handling
iomap: complete partial direct I/O writes synchronously
iomap: mark newly allocated buffer heads as new
fs: factor out a __generic_write_end helper
