Description : minimize filesystem caching effects
The nocache tool tries to minimize the effect an application has on the
Linux file system cache. This is done by intercepting the open and close
system calls and calling posix_fadvise with the POSIX_FADV_DONTNEED
parameter. Because the library remembers which pages (ie., 4K-blocks of the
file) were already in file system cache when the file was opened, these will
not be marked as "don't need", because other applications might need that,
although they are not actively used (think: hot standby).
Use case: backup processes that should not interfere with the present state
of the cache.
