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@xxxxxxxxxxxxxxxxxx>
----------------------------------------------------------------
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
