Subject: Updated VM statistics patch
Date: Fri, 13 Jul 2001 00:15:25 -0300 (BRT) [thread overview]
Message-ID: <Pine.LNX.4.21.0107130003030.2821-100000@freak.distro.conectiva> (raw)
Hi,
I've updated the VM statistics patch. The following changed:
- Added CONFIG_VM_STATS option and Configure.help documentation
- Added Documentation/vm/statistics file which has a description
of each stats field.
- Added more statistics:
vm_pgagescan: pages scanned by refill_inactive_scan()
vm_pgagedown: pages aged down by refill_inative_scan()
vm_pgageup: pages aged up by refill_inactive_scan()/try_to_swap_out()
vm_pgdeactfail_age: nr of deactivation failures on refill_inactive_scan()
due to >0 age
vm_pgdeactfail_ref: nr of deactivation failures on refill_inactive_scan()
due to zero aged pages with more users than the pagecache
vm_ptescan: nr of present ptes scanned by swap_out()
vm_pteunmap: nr of present ptes unmapped by swap_out()
- Changed the vmstat.c hack to not report separated per-zone information
by default, making the output more readable. If needed the per-zone
information can be seen with the "-z" option.
Kernel patch (vmstatistics.patch) plus vmstat patch (vmstat.patch) plus
vmstat.c itself at
