    inalloc    -  Number of allocated inodes.
    infree     -  Number of free inodes.
    inmax      -  Number of maximum inodes.
    dentries   -  Dirty directory cache entries.

    wantpages  -  Pages that are requested by the system when memory is short.

METHODS

new()

Call "new()" to create a new object.

    my $lxs = Sys::Statistics::Linux::FileStats->new;

It's possible to set the path to the proc filesystem.

     Sys::Statistics::Linux::FileStats->new(
        files => {
            # This is the default
            path     => '/proc',
            file_nr  => 'sys/fs/file-nr',
            inode_nr => 'sys/fs/inode-nr',
            dentries => 'sys/fs/dentry-state',
        }
    );

get()

Call "get()" to get the statistics. "get()" returns the statistics as a hash reference.
