Subject: blockd: unmount device explicitly when it disappears
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=3bb3352a5f6c1cffd8a487b92eb762c857df75ed;p=oweals%2Ffstools.git

blockd: unmount device explicitly when it disappears

To keep autofs behavior consistent blockd should request both: mounting
and unmounting when needed. It's important as autofs-related actions may
require slightly different handling.

Without this patch:
1) autofs mounts were handled using TYPE_AUTOFS
2) autofs unmounts were handled using TYPE_HOTPLUG
