Message-ID: <20100707112247.8237.qmail@sourceware.org> List-Id: To: lvm-devel@redhat.com MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit CVSROOT: /cvs/lvm2 Module name: LVM2 Changes by: prajnoha at 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.
