f2fs: fix inode rwsem regression

Browse source

This is similar to 942491c9e6 ("xfs: fix AIM7 regression")
Apparently our current rwsem code doesn't like doing the trylock, then
lock for real scheme.  So change our read/write methods to just do the
trylock for the RWF_NOWAIT case.

We don't need a check for IOCB_NOWAIT and !direct-IO because it
is checked in generic_write_checks().
