Subject: [PATCH tip/core/rcu 2/4] doc: Repair some whitespace damage
Date: Tue, 26 Mar 2019 16:04:30 -0700 [thread overview]
Message-ID: <20190326230432.17963-2-paulmck@linux.ibm.com> (raw)
In-Reply-To: <20190326230408.GA17069@linux.ibm.com>
From: Tycho Andersen <tycho@tycho.ws>
A diagram in whatisRCU.txt has space character before tabs. This commit
therefore makes this diagram consistent with elsewhere in the document:
Use one leading tab, followed by spaces for any additional whitespace
required.
