| |
Introduce a new file /proc/<pid>/blockio (and equivalently per-thread /proc/<pid>/task/<tid>/blockio files) to export per block device i/o statistics of each process to userspace applications.
The objective of this patch is to provide an efficient method to quickly identify the top i/o consumers on specific block devices and, more in general, to collect more detailed informations about specific block device usage.
See the documentation (PATCH 1/4) for more information.
Tested against 2.6.27-rc1-mm1.
The all-in-one patch can be found at: http://download.systemimager.org/~arighi/linux/patches/task-io-acct-block/
