-# Bug 963678 - Test discard functionality
-#
-# Test that basic discard (hole punch) functionality works via the fallocate
-# command line tool. Hole punch deallocates a region of a file, creating a hole
-# and a zero-filled data region. We verify that hole punch works, frees blocks
-# and that subsequent reads do not read stale data (caches are invalidated).
-#
-# NOTE: fuse fallocate is known to be broken with regard to cache invalidation
-# up to 3.9.0 kernels. Therefore, FOPEN_KEEP_CACHE is not used in this
-# test (opens will invalidate the fuse cache).
