What are the patches in ftp://oss.sgi.com/projects/xfs/download/patches/2.4.9/?

I have seen both happen. The first problem I noticed was a mailbox that
ended up with only a few messages in it and all of the old messages
missing. I have also seen files that showed in the directory inode but
not in the filesystem, i.e. running ls on a directory would return a list
of file not found errors followed by a few of the files that were left in
the directory. I have also seen pine hang while trying to read a mailbox,
I assume becuase it was trying to get a lock on a file (in one case I
managed to get it to sieze the lock eventually).

The only thing in
ftp://oss.sgi.com/projects/xfs/download/Release-1.0.2/kernel_patches/i386/
at the moment is the 2.4.14 patches. Interestingly enough, I now see them
in the directory above where I found the 2.4.9 patches.
