Subject: block_dump - full path ?
Date: Sat, 05 Sep 2009 23:44:35 +0200 [thread overview]
Message-ID: <899288751@web.de> (raw)
Hi,
i came across the nice debugging feature sysctl vm.block_dump=1 which leaves information on read/write in dmesg for every process.

Sep 5 20:11:19 neoware kernel: pdflush(14): WRITE block 144704600 on sda2
is it possible to log the full path of the process ?
i assume it is a missing feature, correct ?
what about adding full path support, to be enabled with "sysctl vm.block_dump=2" ?
regards
roland
