Subject: [PATCH] proc: register filesystem last
Date: Sat, 10 Mar 2018 01:27:09 +0300 [thread overview]
Message-ID: <20180309222709.GA3843@avx2> (raw)
As soon as register_filesystem() exits, filesystem can be mounted.
It is better to present fully operational /proc.
Of course it doesn't matter because /proc is not modular
but do it anyway.
Drop error check, it should be handled by panicking.
