- * This is a Python extension module written for Obnam, the backup
- * software.
- *
- * This module provides a way to call the posix_fadvise function from
- * Python. Obnam uses this to use set the POSIX_FADV_SEQUENTIAL and
- * POSIX_FADV_DONTNEED flags, to make sure the kernel knows that it will
- * read files sequentially and that the data does not need to be cached.
- * This makes Obnam not trash the disk buffer cache, which is nice.
