Thanks!I just fixed a build issue in one of my patches for an odd config, so please use the latest version of the patchset from here: https://lore.kernel.org/all/20241122174416.1367052-1-surenb@google.com/ (local)updated, thanks!
Hi Andrew,
I just noticed that patches from an old version of my patchset are
present in mm-unstable, more specifically these two:
fb23aacd2a14 "mm: convert mm_lock_seq to a proper seqcount"
549aeb99ccf1 "mm: introduce mmap_lock_speculation_{begin|end}"
Peter will be merging the latest version into tip/perf/core, so this
will cause a conflict at some point.
It should be easy to update them in mm-unstable to the latest version
[1]. I was able to revert the old ones and apply the new ones without
any merge conflict. If possible, please update them instead of
dropping them from mm-unstable. Some patches I'm preparing to post
have dependencies on this patchset.
Thanks,
Suren.
