.\" 2004-11-17, mtk -- updated notes on /proc/loadavg
.\" 2004-12-01, mtk, rtsig-max and rtsig-nr went away in 2.6.8
.\" 2004-12-14, mtk, updated 'statm', and fixed error in order of list
.\" 2005-05-12, mtk, updated 'stat'
.\" 2005-07-13, mtk, added /proc/sys/fs/mqueue/*
.\" 2005-09-16, mtk, Added /proc/sys/fs/suid_dumpable
.\" 2005-09-19, mtk, added /proc/zoneinfo
.\" 2005-03-01, mtk, moved /proc/sys/fs/mqueue/* material to
.\"             mq_overview.7.
.\"
.\" FIXME 2.6.14 has /proc/PID/numa_maps (if CONFIG_NUMA is
.\" enabled); this needs to be documented.
.\" Info on numa_maps can be found in the patch-2.6.14
.\" Changelog, but this is possibly not up to date.
.\"
.\" FIXME 2.6.13 seems to have /proc/vmcore implemented
.\" in the source code, but there is no option available under
.\" 'make xconfig'; eventually this should be fixed, and then info
.\" from the patch-2.6.13 and change log could be used to write an
.\" entry in this man page.
.\"
.\" FIXME cross check against Documentation/filesystems/proc.txt
.\" to see what information could be imported from that file
.\" into this file.
