Merge branch 'for-4.14-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux 

Pull btrfs fixes from David Sterba:
 "We've collected a bunch of isolated fixes, for crashes, user-visible
  behaviour or missing bits from other subsystem cleanups from the past.

  The overall number is not small but I was not able to make it
  significantly smaller. Most of the patches are supposed to go to
  stable"

* 'for-4.14-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux:
  btrfs: log csums for all modified extents
  Btrfs: fix unexpected result when dio reading corrupted blocks
  btrfs: Report error on removing qgroup if del_qgroup_item fails
  Btrfs: skip checksum when reading compressed data if some IO have failed
  Btrfs: fix kernel oops while reading compressed data
  Btrfs: use btrfs_op instead of bio_op in __btrfs_map_block
  Btrfs: do not backup tree roots when fsync
  btrfs: remove BTRFS_FS_QUOTA_DISABLING flag
  btrfs: propagate error to btrfs_cmp_data_prepare caller
  btrfs: prevent to set invalid default subvolid
  Btrfs: send: fix error number for unknown inode types
  btrfs: fix NULL pointer dereference from free_reloc_roots()
  btrfs: finish ordered extent cleaning if no progress is found
  btrfs: clear ordered flag on cleaning up ordered extents
  Btrfs: fix incorrect {node,sector}size endianness from BTRFS_IOC_FS_INFO
  Btrfs: do not reset bio->bi_ops while writing bio
  Btrfs: use the new helper wbc_to_write_flags
