[GIT PULL] Btrfs for 4.13

From: David Sterba
Date: Tue Jul 04 2017 - 11:21:49 EST


please pull the following btrfs changes. As agreed, the pull request comes from
me because Chris is on vacation. The changelog is below.

There are conflicts with the recently merged block layer branch, the
resolutions are a bit tedious but still straightforward. Stephen sent a mail
about that [1]. You can find my merge at for-4.13-part1-merged, there might be
some whitespace formatting differences but the result is the same.

The core updates improve error handling (mostly related to bios), with the
usual incremental work on the GFP_NOFS (mis)use removal, refactoring or
cleanups. Except the two top patches, all have been in for-next for an
extensive amount of time.

User visible changes:
* statx support
* quota override tunable
* improved compression thresholds
* obsoleted mount option alloc_start

Core updates:
* bio-related updates
- faster bio cloning
- no allocation failures
- preallocated flush bios
* more kvzalloc use, memalloc_nofs protections, GFP_NOFS updates
* prep work for btree_inode removal
* dir-item validation
* qgoup fixes and updates
* cleanups
- removed unused struct members, unused code, refactoring
- argument refactoring (fs_info/root, caller -> callee sink)
- SEARCH_TREE ioctl docs
