Subject: bdi cleanups v3
Date: Fri, 24 Jul 2020 09:32:59 +0200
Message-ID: <20200724073313.138789-1-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 v2:
 - fix a rw_page return value check
 - fix 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
