Hi. I have a question on __log_wait_for_space() in jbd/checkpoint.c while I read jbd code of Linux 2.6.30.4 In __log_wait_for_space(), it releases and re-takes journal->j_state_lock in while loop (at line 139). After the retaking the lock, it checks 'space_left < nblocks'. It seems that it considers that the journal might be written during the lock releasing and re-taking. Then, is it necessary to check 'journal->j_flags & JFS_ABORT' again too? I found that journal_t's j_flags is synchronized via j_state_lock. So, is there any possiblity that j_flags value can be changed during the lock releasing and re-taking?
