Subject: [PATCH] docs: proc.rst: fix wrong time unit
Date: Thu, 3 Mar 2022 00:11:16 +0800 [thread overview]
Message-ID: <20220302161122.3984304-1-uuuuuu@protonmail.com> (raw)
From: YI <afctgo@gmail.com>
Dear Trivial Patch Monkey,
This commit fixes a small documentaion problem reported in
https://bugzilla.kernel.org/show_bug.cgi?id=194593.
Some fields in the file /proc/$pid/stat represent time.
Their units are clock_t, not jiffies as stated in the documentation.
This commit fixes https://bugzilla.kernel.org/show_bug.cgi?id=194593.
