Hi Linus,
This is the main block pull request for 5.1. Not a huge amount of
changes in this round, the biggest one is that we finally have Mings
multi-page bvec support merged. Apart from that, this pull request
contains:
- Small series that avoids quiescing the queue for sysfs changes that
match what we currently have (Aleksei)
- Series of bcache fixes (via Coly)
- Series of lightnvm fixes (via Mathias)
- NVMe pull request from Christoph. Nothing major, just SPDX/license
cleanups, RR mp policy (Hannes), and little fixes (Bart, Chaitanya).
- BFQ series (Paolo)
- Save blk-mq cpu -> hw queue mapping, removing a pointer indirection
for the fast path (Jianchao)
- fops->iopoll() added for async IO polling, this is a feature that the
upcoming io_uring interface will use (Christoph, me)
- Partition scan loop fixes (Dongli)
- mtip32xx conversion from managed resource API (Christoph)
- cdrom registration race fix (Guenter)
- MD pull from Song, two minor fixes.
- Various documentation fixes (Marcos)
- Multi-page bvec feature. This brings a lot of nice improvements with
it, like more efficient splitting, larger IOs can be supported without
growing the bvec table size, and so on. (Ming)
- Various little fixes to core and drivers.
Note that this will throw a merge conflict, due to the late revert of
the gfs2 commit ""gfs2: read journal in large chunks to locate the
head". The resolution is trivial, since it's just deleting the code.
Please pull!
