Subject: ceph: pass down the flags to grab_cache_page_write_begin
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=4a357f5069428afc7c48cb4bdc95c864b7a5c862;p=linux.git

ceph: pass down the flags to grab_cache_page_write_begin

write_begin operations are passed a flags parameter that we need to
mirror here, so that we don't (e.g.) recurse back into filesystem code
inappropriately.
