*	jfs: Fix FITRIM argument handling	Lukas Czerner	2012-10-17	1	-6/+10
\| \| \| \| \| \| \| \| \| \| \| \| \| \|	Currently when 'range->start' is beyond the end of file system nothing is done and that fact is ignored, where in fact we should return EINVAL. The same problem is when 'range.len' is smaller than file system block. Fix this by adding check for such conditions and return EINVAL appropriately.

*	fs/jfs: TRIM support for JFS Filesystem	Tino Reichardt	2012-09-17	1	-0/+117
	This patch adds support for the two linux interfaces of the discard/TRIM command for SSD devices and sparse/thinly-provisioned LUNs. JFS will support batched discard via FITRIM ioctl and online discard with the discard mount option.
