Subject[GIT PULL] Btrfs fixes for 4.16-rc4

please consider the follwing btrfs updates, there are bugfixes or fixes
for user visible behaviour.

No merge conflicts. Please pull, thanks.

- when NR_CPUS is large, a SRCU structure can significantly inflate size
of the main filesystem structure that would not be possible to
allocate by kmalloc, so the kvalloc fallback is used

- improved error handling

- fix endiannes when printing some filesystem attributes via sysfs, this
is could happen when a filesystem is moved between different endianity

- send fixes: the NO_HOLE mode should not send a write operation for a
file hole

- fix log replay for for special files followed by file hardlinks

- fix log replay failure after unlink and link combination

- fix max chunk size calculation for DUP allocation

The following changes since commit fd649f10c3d21ee9d7542c609f29978bdf73ab94:

btrfs: Fix use-after-free when cleaning up fs_devs with a single stale device (2018-02-05 17:15:14 +0100)
