#     Merge tag 'cleanup-kernel_read_write' of git://git.infradead.org/users/hch/misc
#     
#     Pull in-kernel read and write op cleanups from Christoph Hellwig:
#      "Cleanup in-kernel read and write operations
#     
#       Reshuffle the (__)kernel_read and (__)kernel_write helpers, and ensure
#       all users of in-kernel file I/O use them if they don't use iov_iter
#       based methods already.
#     
#       The new WARN_ONs in combination with syzcaller already found a missing
#       input validation in 9p. The fix should be on your way through the
#       maintainer ASAP".
#     
#     [ This is prep-work for the real changes coming 5.9 ]
