[PATCH] reiserfs: add missing D-cache flushing
Looks like, reiserfs_prepare_file_region_for_write() doesn't contain several flush_dcache_page() calls. Found with help from Dmitriy Monakhov <dmonakhov@openvz.org> [akpm@osdl.org: small speedup] Signed-off-by: Alexey Dobriyan <adobriyan@openvz.org> Cc: Dmitriy Monakhov <dmonakhov@openvz.org> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
