Subject: [PATCH 0/3] btrfs-progs: remove full /dev scanning
Date: Wed, 20 Aug 2014 17:21:01 -0500	[thread overview]
Message-ID: <53F51F4D.2090203@redhat.com> (raw)

btrfs fileystem show and btrfs device scan today both have
the "-d" option to scan everything under /dev.  But we also
have a mechanism to scan everything in /proc/partitions, which
should always be sufficient.

If anyone knows why we'd find something deep under /dev but
not in /proc/partitions, speak now or forever hold your peace...

Tested this by running through a matrix of -d, -m, or "" args
for show/scan, for a 2-device fs, with and without a symlinked
device, with and without a symlinked mountpoint.  All output was
identical.

Thanks,
-Eric
