JFS: performance patch
Basically, we saw a large amount of time spent in the jfs_strfromUCS_le() function, mispredicting the branch inside the loop, so I just added some unlikely modifiers to the if statements to re-ordered the code. Again, these simple changes provided > 2 % on spec-sfs, so please consider it for inclusion. Signed-off-by: Dave Kleikamp <shaggy@austin.ibm.com>
