Oops, setting minlen in jfs_ioc_trim() was again wrong :/
I changed this if (minlen < 0) minlen = 1;
to this: if (minlen <= 0) minlen = 1;
This is important, since fstrim() sets it to zero.
Fully working patch is located here: http://www.mcmilk.de/projects/jfs-trim/linux-tree/jfs-trim-2012-08-01_v2.diff
