Subject: io_uring: don't repeat valid flag list
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=c11368a57be460de889696f6ff8815fbcacf4db2;p=linux.git

io_uring: don't repeat valid flag list

req->flags stores all sqe->flags. After checking that sqe->flags are
valid set if IOSQE* flags, no need to double check it, just forward them
all.
