Subject: io_uring/poll: improve readability of poll reference decrementing
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=3cdc4be114a9be61b7041a53e44aa71718a7cf28;p=users%2Fjedix%2Flinux-maple.git

io_uring/poll: improve readability of poll reference decrementing

This overly long line is hard to read. Break it up by AND'ing the
ref mask first, then perform the atomic_sub_return() with the value
itself.
