## Simple tools for checking & influencing filesystem cache content on POSIX systems

While the pagecache tools have historically been developped & tested on some other systems, they are now mostly used/tested on Linux.

### drop-from-pagecache

Asks the system to remove files content from the pagecache using `posix_fadvise()`.

### prefetch-to-pagecache

Asks the system to prefetch files content to the pagecache using `posix_fadvise()`.

### is-in-pagecache

Check if some part of the content of files are in the pagecache (using `mincore()`).

### slices-in-pagecache

Display which parts of the content of files (if any) are in the pagecache (using `mincore()`).

### hrr

Simple random reader program with optional hints to the pagecache.

Both POSIX (`posix_fadvise()`) and Linux specific (`readahead()`) hints are supported.
