Subject: Documentation: sysrq: update description about sysrq crash
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=a8f2a68e42d19e6fc1e0eb6eaef548ef07b19d75;p=linux.git

Documentation: sysrq: update description about sysrq crash

After commit 8341f2f222d7 ("sysrq: Use panic() to force a crash"),
a crash was not generated by dereferencing a NULL pointer anymore.

Let's update documentation as well to make it less misleading.
