I've been watching how many btrfs_search_slot()'s we do and I noticed that when we create a file with selinux enabled we were doing 2 each time we initialize the security context. That's because we lookup the xattr first so we can delete it if we're setting a new value to an existing xattr. But in the create case we don't have any xattrs, so it is completely useless to have the extra lookup. So re-arrange things so that we only lookup first if we specifically have XATTR_REPLACE. That way in the basic case we only do 1 search, and in the more complicated case we do the normal 2 lookups. Thanks, Signed-off-by: NJosef Bacik <josef@redhat.com>

Snapshot creation has two phases. One is the initial snapshot setup, and the second is done during commit, while nobody is allowed to modify the root we are snapshotting. The delayed metadata insertion code can break that rule, it does a delayed inode update on the inode of the parent of the snapshot, and delayed directory item insertion. This makes sure to run the pending delayed operations before we record the snapshot root, which avoids corruptions. Signed-off-by: NChris Mason <chris.mason@oracle.com>

The recent commit to get rid of our trans_mutex introduced some races with block group relocation. The problem is that relocation needs to do some record keeping about each root, and it was relying on the transaction mutex to coordinate things in subtle ways. This fix adds a mutex just for the relocation code and makes sure it doesn't have a big impact on normal operations. The race is really fixed in btrfs_record_root_in_trans, which is where we step back and wait for the relocation code to finish accounting setup. Signed-off-by: NChris Mason <chris.mason@oracle.com>

We can lockup if we try to allow new writers join the transaction and we have flushoncommit set or have a pending snapshot. This is because we set no_trans_join and then loop around and try to wait for ordered extents again. The problem is the ordered endio stuff needs to join the transaction, which it can't do because no_trans_join is set. So instead wait until after this loop to set no_trans_join and then make sure to wait for num_writers == 1 in case anybody got started in between us exiting the loop and setting no_trans_join. This could easily be reproduced by mounting -o flushoncommit and running xfstest 13. It cannot be reproduced with this patch.

Josef recently changed the free extent cache to look in the block group cluster for any bitmaps before trying to add a new bitmap for the same offset. This avoids BUG_ON()s due covering duplicate ranges. But it didn't go quite far enough. A given free range might span between one or more bitmaps or free space entries. The code has looping to cover this, but it doesn't check for clustered bitmaps every time. This shuffles our gotos to check for a bitmap in the cluster for every new bitmap entry we try to add.

I was testing with empty_cluster = 0 to try and reproduce a problem and kept hitting early enospc panics. This was because our loop logic was a little confused. So this is what I did 1) Make the loop variable the ultimate decider on wether we should loop again isntead of checking to see if we had an uncached bg, empty size or empty cluster. 2) Increment loop before checking to see what we are on to make the loop definitions make more sense. 3) If we are on the chunk alloc loop don't set empty_size/empty_cluster to 0 unless we didn't actually allocate a chunk. If we did allocate a chunk we should be able to easily setup a new cluster so clearing empty_size/empty_cluster makes us less efficient. This kept me from hitting panics while trying to reproduce the other problem. Thanks, Signed-off-by: NJosef Bacik <josef@redhat.com>

In cleaning up the clustering code I accidently introduced a regression by adding bitmap entries to the cluster rb tree. The problem is if we've maxed out the number of bitmaps we can have for the block group we can only add free space to the bitmaps, but since the bitmap is on the cluster we can't find it and we try to create another one. This would result in a panic because the total bitmaps was bigger than the max bitmaps that were allowed. This patch fixes this by checking to see if we have a cluster, and then looking at the cluster rb tree to see if it has a bitmap entry and if it does and that space belongs to that bitmap, go ahead and add it to that bitmap. I could hit this panic every time with an fs_mark test within a couple of minutes. With this patch I no longer hit the panic and fs_mark goes to completion.

I noticed when running an enospc test that we would get stuck committing the transaction in check_data_space even though we truly didn't have enough space. So check to see if bytes_pinned is bigger than num_bytes, if it's not don't commit the transaction. Thanks, Signed-off-by: NJosef Bacik <josef@redhat.com>

When profiling the find cluster code it's hard to tell where we are spending our time because the bitmap and non-bitmap functions get inlined by the compiler, so make that not happen. Thanks, Signed-off-by: NJosef Bacik <josef@redhat.com>
