[PATCH 0/3] xfstests: improvements for generic/204

[Dave Chinner]

Hi folks,

These patches are fixes and improvements for generic/204.

Firstly, it doesn't check the filesystem it works on, and so
corruptions can go undetected. Secondly, _scratch_mkfs_sized doesn't
handle different block sizes passed in on the command line via
MKFS_OPTIONS at all well (i.e they get ignored) and so it has never
run on small block size filesystems of any type.

Finally, make it run on filesystems with different block sizes and
inode sizes by scaling the file count appropriately. It detects
block and inode size from the output of mkfs, so scaling only occurs
if the underlying filesystem emits them.

Cheers,

Dave.
