[PATCH] Doc: vm/hugetlbpage update-2
Add new line of /proc/meminfo output.
Explain the HugePage_ lines in /proc/meminfo (from Bill Irwin).
Change KB to kB since the latter is what is used in the kernel.

It's vaguely analogous to overcommit. /proc/filesystems should also show a filesystem of type "hugetlbfs" configured in the kernel. |
