#     Merge tag 'io_uring-5.5-2020-01-26' of git://git.kernel.dk/linux-block
#     
#     Pull io_uring fixes from Jens Axboe:
#      "Fix for two regressions in this cycle, both reported by the postgresql
#       use case.
#     
#       One removes the added restriction on who can submit IO, making it
#       possible for rings shared across forks to do so. The other fixes an
#       issue for the same kind of use case, where one exiting process would
#       cancel all IO"
#     
#     * tag 'io_uring-5.5-2020-01-26' of git://git.kernel.dk/linux-block:
#       io_uring: don't cancel all work on process exit
#       Revert "io_uring: only allow submit from owning task"

WARNING: vmlinux.o(.text.unlikely+0x5d0): Section mismatch in reference from the function free_memmap() to the function .meminit.text:memblock_free()
The function free_memmap() references
the function __meminit memblock_free().
This is often because free_memmap lacks a __meminit 
annotation or the annotation of memblock_free is wrong.
