Subject: [bug report] ext4, project: expand inode extra size if possible
Date: Mon, 2 Dec 2019 12:41:04 +0300 [thread overview]
Message-ID: <20191202094103.rgqihwzoxxy676fj@kili.mountain> (raw)
Hello Miao Xie,
The patch c03b45b853f5: "ext4, project: expand inode extra size if
possible" from Aug 6, 2017, leads to the following static checker
warning:
fs/ext4/inode.c:5708 ext4_expand_extra_isize()
warn: inconsistent returns 'EXT4_I(inode)->xattr_sem'.
Locked on : 5708
Unlocked on: 5708
fs/ext4/inode.c
5681 handle = ext4_journal_start(inode, EXT4_HT_INODE,
5682 EXT4_DATA_TRANS_BLOCKS(inode->i_sb));
5683 if (IS_ERR(handle)) {
5684 error = PTR_ERR(handle);
5685 brelse(iloc->bh);
5686 return error;
5687 }
5688
5689 ext4_write_lock_xattr(inode, &no_expand);
5690
5691 BUFFER_TRACE(iloc->bh, "get_write_access");
5692 error = ext4_journal_get_write_access(handle, iloc->bh);
5693 if (error) {
5694 brelse(iloc->bh);
5695 goto out_stop;
Shouldn't this goto the ext4_write_unlock_xattr()?
5696 }
5697
5698 error = __ext4_expand_extra_isize(inode, new_extra_isize, iloc,
5699 handle, &no_expand);
5700
5701 rc = ext4_mark_iloc_dirty(handle, inode, iloc);
5702 if (!error)
5703 error = rc;
5704
5705 ext4_write_unlock_xattr(inode, &no_expand);
5706 out_stop:
5707 ext4_journal_stop(handle);
5708 return error;
5709 }
regards,
dan carpenter
