Subject: 2.6.28 /proc/diskstats
Date: Sun, 12 Apr 2009 02:00:08 +0100	[thread overview]
Message-ID: <49E13D18.2090805@solemnwarning.net> (raw)

Hi

Since 2.6.28, fd0 isn't visible in /proc/diskstats from boot, only after 
access/mount. It is visible in /sys/block/ from boot, so there are no 
issues detecting it. This may also affect other devices such as hda but 
I haven't tested this yet, my test system and QEMU both only have 
ram0-ram15 from boot. I have tested 2.6.30-rc1 and found the same 
behavior. Is this a bug or a deliberate change?

Thanks
