Merge branch 'master' into staging-next
There ver very many conflicts, basically all due to
name -> pname+version.  Fortunately, almost everything was auto-resolved
by kdiff3, and for now I just fixed up a couple evaluation problems,
as verified by the tarball job.  There might be some fallback to these
conflicts, but I believe it should be minimal.

# This patch shuffles the name of the io_uring memory barrier primitives.
# They were using extremely common names by accident, which caused
# namespace conflicts with many other projects using the same names. Note:
# this does not change the user-visible API of liburing (liburing is
# designed exactly to hide the necessary memory barriers when using the
# io_uring syscall directly). It only changes the names of some internals.
# The only reason this caused problems at all is because memory barrier
# primitives are written as preprocessor defines, in a common header file,
# which get included unilaterally.
#
# Already upstream: remove when moving to the next version
