Ever wanted to use AMOS on a MultiUserFS partition?
Ever wanted to play Worms(DC) on a MultiUserFS partition?
And what about all the other progs, which can't get files stored on your MuFS
partition?
- - Here's the fix..!

Background:
AmigaDOS has a function to lock a file to prevent it from being altered while a
program uses it. This lock can be defined in two ways:
1: Shared - for reading - ($fffffffe, or -2 for ordinary humans... :)
2: Exclusive - for writing - ($ffffffff, or -1 for ordinary humans... :)
Now there's just one little problem:
What about all the other 4294967294 (2³²-2) different possibilities when using a
32bit integer?
FastFileSystem assumes that if it isn't an exclusive lock it must be a shared one.
MultiUserFileSystem, on the other hand, concludes that if it isn't an exclusive or
a shared lock, it simply can't be a valid lock.
MuFS's conclusion is perfectly okay, if it haven't been for all those dumb coders
with too much lumpy gravy for brains --- FIX YOUR CODE NOW!!!
This little patch makes all filesystems act like FFS when dealing with locks.
