# 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

# Finally, this patch fixes the aarch64-linux support introduced by the
# first patch, but which was _broken_ by the second patch, in a horrid
# twist of fate: it neglected to change the names of the aarch64 barriers
# appropriately.
