[PATCH v2 0/6] Miscellaneous DAX patches, take 2

[Matthew Wilcox <matthew.r.wilcox@intel.com>]

A miscellaneous set of patches to improve DAX.  All are independent of
each other.

I dropped the DAX mmap support for block devices; I started trying
to put in a sysfs toggle and ran into some difficulties, so just drop
that part of the patch for now.  There's no problem (that I know of)
with the read()/write() portion of the patch.

I fixed up the conflict between Dave Chinner's changes to ext4 and mine.

I forgot the 'bdev_direct_access() may sleep' patch in the previous
submission.

Matthew Wilcox (6):
  dax: Add block size note to documentation
  dax: Use copy_from_iter_nocache
  ext4: Use ext4_get_block_write() for DAX
  vfs: Allow truncate, chomd and chown to be interrupted by fatal
    signals
  block: Add support for DAX reads/writes to block devices
  dax: bdev_direct_access() may sleep
