This commit has a (reasonably simple) conflict against commit

  6551d5c56eb0 ("pipe: make sure to wake up everybody when the last reader/writer closes")

from Linus' tree.

Also a semantic conflict against commit

  52b31bc9aabc ("io_uring: add splice(2) support")

from the block tree needing this fix up (white space damaged)

And these have a conflict against commitinclude/linux/lsm_hooks.h

  98e828a0650f ("security: Refactor declaration of LSM hooks")

from the bpf-next tree (will be in the net-next tree pull).  That
requires taking the net-next version of include/linux/lsm_hooks.h and
then applying the following patch:
