Subject: [PATCH v3 6/7] drivers/staging/rtl8188eu: convert event_seq to use seqnum_ops
Date: Wed, 3 Feb 2021 11:12:02 -0700 [thread overview]
Message-ID: <5bee25950b546b28e03a7c71cb494ff1b2ded083.1612314468.git.skhan@linuxfoundation.org> (raw)
In-Reply-To: <cover.1612314468.git.skhan@linuxfoundation.org>
Sequence Number api provides interfaces for unsigned atomic up counters
leveraging atomic_t and atomic64_t ops underneath. Convert it to use
seqnum_ops.
event_seq atomic_t variables are atomic counters. Convert them to use
seqnum_ops.
