Subject: [PATCH 11/20] hpfs: move to drivers/staging
hpfs has not seen a single patch from its maintainer
since the start of the git history, and the user base
seems to be completely gone after the end of OS/2.
I have tried to keep the file system alive as much
as possible through the BKL removal, but this its
time seems to have come. If we can find an actual
user who is willing to test patches, or even a
maintainer that can work on the code, it can easily
be moved back into the main tree.
If that does not happen, it will get removed from
the kernel tree after a few releases in staging/.
