btrfs: abort transaction on generation mismatch when marking eb as dirty

btrfs: abort transaction on generation mismatch when marking eb as dirty
[ Upstream commit 50564b651d01c19ce732819c5b3c3fd60707188e ]
When marking an extent buffer as dirty, at btrfs_mark_buffer_dirty(), we check if its generation matches the running transaction and if not we just print a warning. Such mismatch is an indicator that something really went wrong and only printing a warning message (and stack trace) is not enough to prevent a corruption. Allowing a transaction to commit with such an extent buffer will trigger an error if we ever try to read it from disk due to a generation mismatch with its parent generation.
So abort the current transaction with -EUCLEAN if we notice a generation mismatch. For this we need to pass a transaction handle to btrfs_mark_buffer_dirty() which is always available except in test code, in which case we can pass NULL since it operates on dummy extent buffers and all test roots have a single node/leaf (root node at level 0).

btrfs: bail out of uuid tree scanning if we're closing
In doing my fsstress+EIO stress testing I started running into issues where umount would get stuck forever because the uuid checker was chewing through the thousands of subvolumes I had created.
We shouldn't block umount on this, simply bail if we're unmounting the fs. We need to make sure we don't mark the UUID tree as ok, so we only set that bit if we made it through the whole rescan operation, but otherwise this is completely safe.

btrfs: return the actual error value from from btrfs_uuid_tree_iterate
In function btrfs_uuid_tree_iterate(), errno is assigned to variable ret on errors. However, it directly returns 0. It may be better to return ret. This patch also removes the warning, because the caller already prints a warning.

btrfs: remove root parameter from transaction commit/end routines
Now we only use the root parameter to print the root objectid in a tracepoint. We can use the root parameter from the transaction handle for that. It's also used to join the transaction with async commits, so we remove the comment that it's just for checking.

Btrfs: make btrfs_search_forward return with nodes unlocked
None of the uses of btrfs_search_forward() need to have the path nodes (level >= 1) read locked, only the leaf needs to be locked while the caller processes it. Therefore make it return a path with all nodes unlocked, except for the leaf.
This change is motivated by the observation that during a file fsync we repeatdly call btrfs_search_forward() and process the returned leaf while upper nodes of the returned path (level >= 1) are read locked, which unnecessarily blocks other tasks that want to write to the same fs/subvol btree. Therefore instead of modifying the fsync code to unlock all nodes with level >= 1 immediately after calling btrfs_search_forward(), change btrfs_search_forward() to do it, so that it benefits all callers.
