To reset the peak resident set size ("high water mark") to the process's
current value:

The /proc/pid/pagemap gives the PFN, which can be used to find the pageflags
using /proc/kpageflags and number of times a page is mapped using
/proc/kpagecount. For detailed explanation, see Documentation/vm/pagemap.txt.

=======================
Squashfs is a compressed read-only filesystem for Linux.
It uses zlib/lzo/xz compression to compress files, inodes and directories.
Inodes in the system are very small and all blocks are packed to minimise
data overhead. Block sizes greater than 4K are supported up to a maximum
of 1Mbytes (default block size 128K).

Squashfs is intended for general read-only filesystem use, for archival
