	Jason's lseek series.  One note: after that no_llseek is defined
to NULL; boilerplate initializers ought to be removed, but that's better
done at the end of merge window - fewer conflicts that way.  Could you run

git grep -l -w no_llseek | grep -v porting.rst | while read i; do
	sed -i '/\<no_llseek\>/d' $i
done

just before -rc1 to take that boilerplate out?

  fs: remove no_llseek (2022-07-16 09:19:47 -0400)

----------------------------------------------------------------
	Saner handling of "lseek should fail with ESPIPE" - gets rid of
magical no_llseek thing and makes checks consistent.  In particular,
ad-hoc "can we do splice via internal pipe" checks got saner (and
somewhat more permissive, which is what Jason had been after, AFAICT)

Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

----------------------------------------------------------------
Jason A. Donenfeld (6):
      fs: clear or set FMODE_LSEEK based on llseek function
      fs: do not compare against ->llseek
      dma-buf: remove useless FMODE_LSEEK flag
      vfio: do not set FMODE_LSEEK flag
      fs: check FMODE_LSEEK to control internal pipe splicing
      fs: remove no_llseek
