nilfs2: remove unlikely directive causing mis-conversion of error code
The following error code handling in nilfs_segctor_write() function wrongly converted negative error codes to a truth value (i.e. 1): err = unlikely(err) ? : res; which originaly meant to be err = err ? : res; This mis-conversion caused that write or sync functions receive the unexpected error code. This fixes the bug by removing the unlikely directive. Signed-off-by: Ryusuke Konishi <konishi.ryusuke@lab.ntt.co.jp> Cc: stable@kernel.org
