Subject: bdi cleanups v5
Date: Tue, 15 Sep 2020 17:18:17 +0200	[thread overview]
Message-ID: <20200915151829.1767176-1-hch@lst.de> (raw)

Hi Jens,

this series contains a bunch of different BDI cleanups.  The biggest item
is to isolate block drivers from the BDI in preparation of changing the
lifetime of the block device BDI in a follow up series.

Changes since v4:
 - add a back a prematurely removed assignment in dm-table.c
 - pick up a few reviews from Johannes that got lost

Changes since v3:
 - rebased on the lasted block tree, which has some of the prep
   changes merged
 - extend the ->ra_pages changes to ->io_pages
 - move initializing ->ra_pages and ->io_pages for block devices to
   blk_register_queue

Changes since v2:
 - fix a rw_page return value check
 - fix up various changelogs

Changes since v1:
 - rebased to the for-5.9/block-merge branch
 - explicitly set the readahead to 0 for ubifs, vboxsf and mtd
 - split the zram block_device operations
 - let rw_page users fall back to bios in swap_readpage
