[PATCH] lvm2: fix SIGSEGV of dmeventd

[PATCH] lvm2: fix SIGSEGV of dmeventd

[Takahiro Yasui]

Hi,

Around July 16th, 2009, the prototype of logging function was changed and
dm_errno was added as the forth argument. However plugin functions stay
unchanged and dmeventd is killed by the signal (SIGSEGV). This patch adds
the argument, dm_errno, in the plugin functions.
