Hi, why is there a window between statements "err = ext3_journal_get_write_access(handle, this_bh);" and "ext3_journal_dirty_metadata(handle, this_bh);" ? In my test, there is an error in journal_dirty_metadata: jh is null thanks!

[Re-sending to the ext3 list, with minor edits] I'm in the process of fixing errors generated by the Coverity tool on the Linux kernel, and I would like your comment on a set of problems reported in ext3. The main issue reported is not checking the return code of ext3_journal_get_write_access() in various places. I would like to know if there should be error handling in these cases. The places where the return value is not checked are(in the current kernel version): fs/ext3/inode.c ext3_clear_blocks 1829 fs/ext3/namei.c ext3_append 63...
