From: Chao Yu <redacted> register_shrinker in mb_cache_create may fail due to no memory. This patch fixes to do the check of return value of register_shrinker and handle the error case, otherwise mb_cache_create may return with no error, but losing the inner shrinker. Signed-off-by: Chao Yu <redacted> Reviewed-by: Jan Kara <jack@suse.cz>Applied, thanks. (Apologies for the delay; this patch slipped through the cracks.)
Ping, didn't see it in mainline, is this patch still under testing now?
