Ever since the switch to blk-mq, a lower device not used for VM
writeback will not be marked congested, so the check will never
trigger.

Replace BDI_CAP_NO_ACCT_WB with a positive BDI_CAP_WRITEBACK_ACCT to
make the checks more obvious. Also remove the pointless
bdi_cap_account_writeback wrapper that just obsfucates the check.

Replace the two negative flags that are always used together with a
single positive flag that indicates the writeback capability instead
of two related non-capabilities. Also remove the pointless wrappers
to just check the flag.

Set up a readahead size by default, as very few users have a good

Just checking SB_I_CGROUPWB for cgroup writeback support is enough.
Either the file system allocates its own bdi (e.g. btrfs), in which case
it is known to support cgroup writeback, or the bdi comes from the block
layer, which always supports cgroup writeback.

Generate the queue_sysfs_entry given that we have all the required

Drivers shouldn't really mess with the readahead size, as that is a VM
concept. Instead set it based on the optimal I/O size by lifting the
algorithm from the md driver when registering the disk. Also set
bdi->io_pages there as well by applying the same scheme based on
max_sectors.
Add two helpers macros to avoid boilerplate code for the queue sysfs
entries.

The BDI_CAP_STABLE_WRITES is one of the few bits of information in the
backing_dev_info shared between the block drivers and the writeback code.
To help untangling the dependency replace it with a queue flag and a
superblock flag derived from it. This also helps with the case of e.g.

There is no point in trying to call bdev_read_page if SWP_SYNCHRONOUS_IO
is not set, as the device won't support it.

The raid5 and raid10 drivers currently update the read-ahead size,
but not the optimal I/O size on reshape. To prepare for deriving the
read-ahead size from the optimal I/O size make sure it is updated
as well.

BDI_CAP_SYNCHRONOUS_IO is only checked in the swap code, and used to

the method instead. The only complication is that zram needs a second
set of block_device_operations as it can switch between modes that

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
