[PATCH 00/14] Misc transaction cleanups

[Nikolay Borisov <nborisov@suse.com>]

Here are a bunch of transaction-related cleanups all of them present no 
functional changes. The first 2 patches could be more interesting - the first
one moves trans_release_metadata to transaction.c and makes it static and the 
second one opencodes btrfs_write_and_wait_marked_extents in its sole caller
to make the chall chain shorter. The rest of the patches just kill the 
extraneous fs_info argument since they also take either a btrfs_trans_handle or
btrfs_transaction pointer which already contain fs_info. 

The modified functions are all called from btrfs_commit_transaction. With this
series applied the only function which remain that still take fs_info and 
some type of transaction reference are: 

btrfs_finish_extent_commit
btrfs_qgroup_account_extents
btrfs_run_delayed_refs


The reason I haven't touched them is that David expressed some reservation 
about mass cleaning of functions which are more or less public interface. And 
the above 3 are such functions. David if you don't objec to converting those 3
I will keep them in mind when doing further cleanups in the transaction area.
