Bob Peterson 8deedce385 gfs2: Don't call dlm after protocol is unmounted ... [ Upstream commit d1340f80f0 ] In the gfs2 withdraw sequence, the dlm protocol is unmounted with a call to lm_unmount. After a withdraw, users are allowed to unmount the withdrawn file system. But at that point we may still have glocks left over that we need to free via unmount's call to gfs2_gl_hash_clear. These glocks may have never been completed because of whatever problem caused the withdraw (IO errors or whatever). Before this patch, function gdlm_put_lock would still try to call into dlm to unlock these leftover glocks, which resulted in dlm returning -EINVAL because the lock space was abandoned. These glocks were never freed because there was no mechanism after that to free them. This patch adds a check to gdlm_put_lock to see if the locking protocol was inactive (DFL_UNMOUNT flag) and if so, free the glock and not make the invalid call into dlm. I could have combined this "if" with the one that follows, related to leftover glock LVBs, but I felt the code was more readable with its own if clause.
