These jfs_<level> uses need neither a line continuation to assemble
the format strings nor newline terminations in the formats.

Lukas Czerner 4e7a4b0122 jfs: Fix FITRIM argument handling 
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.

Tino Reichardt b40c2e665c fs/jfs: TRIM support for JFS Filesystem 
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.
