fadvise

Native Node.js bindings for the posix_fadvise() function on Linux
============================

Usage:
``javascript
const fadvise = require('fadvise');
const fs = require('fs');

let fd = fs.openSync('./test.tmp', 'a');
fs.writeSync(fd, 'hundreds of megabytes');
fs.fsync(fd, function () {
fadvise.posix_fadvise(fd, 0, 0, fadvise.POSIX_FADV_DONTNEED);
fs.closeSync(fd);
});
`

In the example above, top and nocache's cachestats test.tmp` should indicate 0 (additional) pages in buffers/cache.

See posix_fadvise(7) for details.
