In case a downconvert is queued, and a flock receives a signal, BUG_ON(lockres->l_action != OCFS2_AST_INVALID) is triggered because a lock cancel triggers a dlmunlock while an AST is scheduled. To avoid this, allow a LKM_CANCEL to pass through, and let it wait on __dlm_wait_on_lockres().

ocfs2_read_virt_blocks() does BUG when we try to read a block from a file beyond its end. Since this can happen due to filesystem corruption, it is not really an appropriate answer. Make ocfs2_read_quota_block() check the condition and handle it by calling ocfs2_error() and returning EIO.

In OCFS2, allocator locks rank above transaction start. Thus we cannot extend quota file from inside a transaction less we could deadlock. We solve the problem by starting transaction not already in ocfs2_acquire_dquot() but only in ocfs2_local_read_dquot() and ocfs2_global_read_dquot() and we allocate blocks to quota files before starting the transaction. In case we crash, quota files will just have a few blocks more but that's no problem since we just use them next time we extend the quota file.

In a non-sparse extend, we correctly allocate (and zero) the clusters between the old_i_size and pos, but we don't zero the portions of the cluster we're writing to outside of pos<->len.

Change i_size of global quota files so that it always remains aligned to block size. This is mainly because the end of quota block may contain checksum (if checksumming is enabled) and it's a bit awkward for it to be "outside" of quota file (and it makes life harder for ocfs2-tools).

In ocfs2_adjust_adjacent_records, we will adjust adjacent records according to the extent_list in the lower level. But actually the lower level tree will either be a leaf or a branch. If we only use ocfs2_is_empty_extent we will meet with some problem if the lower tree is a branch (tree_depth > 1). So use !ocfs2_rec_clusters instead. And actually only the leaf record can have holes. So add a BUG_ON for non-leaf branch. Signed-off-by: Tao Ma <tao.ma@oracle.com> Signed-off-by: Joel Becker <joel.becker@oracle.com>

In commit ea455f8a, we moved the dentry lock put process into ocfs2_wq. This causes problems during umount because ocfs2_wq can drop references to inodes while they are being invalidated by invalidate_inodes() causing all sorts of nasty things (invalidate_inodes() ending in an infinite loop, "Busy inodes after umount" messages etc.). We fix the problem by stopping ocfs2_wq from doing any further releasing of inode references on the superblock being unmounted, wait until it finishes the current round of releasing and finally cleaning up all the references in dentry_lock_list from ocfs2_put_super(). The issue was tracked down by Tao Ma <tao.ma@oracle.com>. Signed-off-by: Jan Kara <jack@suse.cz> Signed-off-by: Joel Becker <joel.becker@oracle.com>

In normal tree rotation left process, we will never touch the tree branch above subtree_index and ocfs2_extend_rotate_transaction doesn't reserve the credits for them either. But when we want to delete the rightmost extent block, we have to update the rightmost records for all the rightmost branch(See ocfs2_update_edge_lengths), so we have to allocate extra credits for them. What's more, we have to access them also. Signed-off-by: Tao Ma <tao.ma@oracle.com> Signed-off-by: Joel Becker <joel.becker@oracle.com>

The f_dev in _request_firmware() is allocated via the fw_setup_device() and fw_register_device() calls and its class set to firmware_class (the class release function is fw_dev_release). Commit 6acf70f0 replaced the kfree(dev) in fw_dev_release() with a put_device() call but my understanding is that the release function is called via put_device -> kobject_put -> kref_put -> koject_release etc. and it should call kfree since it's the last to see this device structure alive. Because of that, the _request_firmware() function on its -ENOENT error path only calls device_unregister(f_dev) which would eventually call fw_dev_release() but there is no kfree (the subsequent put_device call would just make the kref negative).
