if strict overcommit accounting is enabled (mode 2 in

The CommitLimit is calculated with the following formula:
- CommitLimit = ('vm.overcommit_ratio' * Physical RAM) + Swap
+ CommitLimit = ([total RAM pages] - [total huge TLB pages]) *
+ overcommit_ratio / 100 + [total swap pages]
For example, on a system with 1G of physical RAM and 7G
of swap with a `vm.overcommit_ratio` of 30 it would
yield a CommitLimit of 7.3G.

This file provides information associated with an opened file. The regular

+created with [see open(2) for details] and 'mnt_id' represents mount ID of

A typical output is
pos: 0
