Subject: LVM2 ./WHATS_NEW_DM udev/10-dm.rules.in udev/1 ...
Date: Wed, 07 Jul 2010 11:22:00 -0000 [thread overview]
Message-ID: <20100707112247.8237.qmail@sourceware.org> (raw)
CVSROOT: /cvs/lvm2
Module name: LVM2
Changes by: prajnoha@sourceware.org 2010-07-07 11:22:46
Modified files:
. : WHATS_NEW_DM
udev : 10-dm.rules.in 11-dm-lvm.rules
Log message:
Use "nowatch" udev rule for known inappropriate devices.
For now, this is just a precaution. Normally, all the other (non-dm) rules
should check DM_UDEV_DISABLE_OTHER_RULES_FLAG and therefore avoid setting
any inotify watches as well. But let's make sure.
Support for final assignment of the "nowatch" rule (the use of ":=") will
appear in next udev release, v160. This should also work in previous udev
versions but the setting won't be sealed so any further OPTIONS="watch" will
always prevail there.
We may want to add more specific "nowatch" rules later if needed.
