Subject: [PATCH] io_uring: don't check req->file in io_fsync_prep()
Git-commit: ec858afda857e361182ceafc3d2ba2b164b8e889
Patch-mainline: v5.18-rc2
References: bsc#1205205

This is a leftover from the really old days where we weren't able to
track and error early if we need a file and it wasn't assigned. Kill
the check.
