Filipe Manana c7cbc1cd61 generic: test for number of bytes used by files after buffered writes
Test that a filesystem's implementation of the stat(2) system call
reports correct values for the number of blocks allocated for a file
when there are delayed allocations.

This test is motivated by a bug in btrfs which is fixed by the
following path for the linux kernel:

 "Btrfs: fix reported number of inode blocks"
