SubjectUpdate of quota patches
  Hello.

I'm sending you update of my quota patches. There are fixed some
syscall issues on ia64, sparc64 and s390x architectures. There's
also one small bugfix (or maybe new feature :)) - general users
are now allowed to get information about quota files. The incremental
patch is attached. Patch with whole new quota format stuff can be found at
(to be applied after quota-fix-2.4.3-1.diff.gz):
ftp://atrey.karlin.mff.cuni.cz/pub/local/jack/quota/v2.4/quota-patch-2.4.3-2.diff.gz
