Subject: [PATCH] Fix /sys/<dev>/<partition>/dev format: %04x -> %u:%u
Date: Tue, 12 Aug 2003 17:30:46 +0200 [thread overview]
Message-ID: <20030812153046.GA13568@chtephan.cs.pocnet.net> (raw)
Hi!
(I already sent a patch to Andrew, but someone just told me that the
vanilla test3 is also affected)
In 2.6.0-test3 a part of the 64 bit kdev_t patch got merged, it changes the
format of /sys/block/<dev>/dev from %02x%02x to %u:%u. The partition could
must also be changed.
e.g. cat /sys/block/hda/hda5/dev should return 3:5 instead of 0305
This small patch adds this:
