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
