From: Andreas Gruenbacher <agruenba@xxxxxxxxxx> [ Upstream commit 3bde4c48586074202044456285a97ccdf9048988 ] When direct writes fail with -ENOTBLK because we're writing into a hole (gfs2_iomap_begin()) or because of a page invalidation failure (iomap_dio_rw()), we're falling back to buffered writes. In that case, when we lose the inode glock in gfs2_file_buffered_write(), we want to re-acquire it instead of returning a short write.
