Subject[PATCH] Enhancement of /proc/partitions output (2.5.1-pre5)
Date
From
Linus,

Please consider below patch which adds the starting sector and number of
sectors to /proc/partitions.

It works fine here and I find having this information output can be very
useful (especially when the values in the kernel don't match the values
output by fdisk for example).

Best regards,

Anton
