Subject: [PATCH 0/9] Remove remaining parts of congestions tracking code.
Date: Thu, 27 Jan 2022 13:46:29 +1100 [thread overview]
Message-ID: <164325106958.29787.4865219843242892726.stgit@noble.brown> (raw)
Congestion hasn't been reliably tracked for quite some time.
Most MM uses of it for guiding writeback decisions were removed in 5.16.
Some other uses were removed in 17-rc1.
This series removes the remaining places that test for congestion, and
the few places which still set it.
The second patch touches a few filesystems. I didn't think there was
much value in splitting this out by filesystems, but if maintainers
would rather I did that, I will.
The f2fs, cephfs, fuse, NFS, and block patches can go through the
respective trees proving the final patch doesn't land until after they
all do - so maybe it should be held for 5.18-rc2 if all the rest lands
by 5.18-rc1.
Thanks,
NeilBrown
