[GIT PULL] Btrfs fixes for 4.16-rc4

[David Sterba]

Hi,

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
  hosts

- 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
