When building bcache as a module, the following errors are silenced by this patch: ERROR: "call_rwsem_down_read_failed" [block/bcache.ko] undefined! ERROR: "call_rwsem_wake" [block/bcache.ko] undefined! There may be implications of the extra code introduced by this, but I am not familiar with these functions. Though I can confirm that the resulting build seems to work. --- block/bcache.c | 4 ++-- 1 files changed, 2 insertions(+), 2 deletions(-)
