Subject: mm, swap: remove redundant comment for read_swap_cache_async
X-Git-Tag: v6.19-rc1~112^2~18
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=f1bae15c6ad59870eca7824c66e40ee7469ee0fd;p=thirdparty%2Flinux.git

mm, swap: remove redundant comment for read_swap_cache_async

The function now manages get/put_swap_device() internally, making the
comment explaining this behavior to callers unnecessary.
