[PATCH v2 0/5] block, dax: updates for 4.4

Show all headers | View raw

Changes since v1: https://lists.01.org/pipermail/linux-nvdimm/2015-October/002538.html

1/ Rename file_bd_inode to bdev_file_inode (Jan Kara)

2/ Clarify sb_start_pagefault() comment (Jan Kara)

3/ Collect Reviewed-by's

---

As requested [1], break out the block specific updates from the dax-gup
series [2], to merge via the block tree.

1/ Enable dax mappings for raw block devices.  This addresses the review
   comments (from Ross and Honza) from the RFC [3].

2/ Introduce dax_map_atomic() to fix races between device teardown and
   new mapping requests.  This depends on commit 2a9067a91825 "block:
   generic request_queue reference counting" in for-4.4/integrity branch
   of the block tree.

3/ Cleanup clear_pmem() and its usage in dax.  This depends on commit
   0f90cc6609c7 "mm, dax: fix DAX deadlocks" that was merged into v4.3-rc6.

These pass the nvdimm unit tests and have passed a 0day-kbuild-robot run.
