treewide: Add __GFP_NOWARN to k.alloc calls with v.alloc fallbacks
Don't emit OOM warnings when k.alloc calls fail when there there is a v.alloc immediately afterwards. Converted a kmalloc/vmalloc with memset to kzalloc/vzalloc. Signed-off-by: Joe Perches <joe@perches.com> Acked-by: "Theodore Ts'o" <tytso@mit.edu> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
