[parisc-linux] journaling filesystem on parisc?

[Matthias Klose]

Did not see this mentioned on the list or the site. Any experiences on
hppa? Does XFS work?

Thanks, Matthias

You could try applying the XFS patches to the kernel for PARISC, and 
I know that they have worked on other RISC architectures(ppc and 
alpha, possibly also sparc), but I'm guessing you might need to do a 
little more work than just kernel compilation

well, it does work with some small tweaks.

i've put a patch out at:
ftp://ftp.parisc-linux.org/patches/xfs-1.0.2-hppa-2.4.17-pa11.diff.gz

it seems to work ok here. i've done some kernel compiles and ran
bonnie++ on it.

I'd like to get some comments on some of the magic numbers in the patch,
and then I hope to commit the parisc specific pieces of the patch since
they aren't really xfs specific. (the following three plus exporting
lclear_user)

first, syscall numbers... are these numbers ok?

There's another one now at 
ftp://ftp.parisc-linux.org/patches/xfs-1.0.2-hppa-2.4.17-pa11-small.diff

This one contains only the hppa changes and is meant to be applied over
parisc linux cvs + the following patches from SGI:

from ftp://oss.sgi.com/projects/xfs/download/patches/2.4.17: 

   xfs-2.4.17-split-only.bz2
   xfs-2.4.17-split-kernel.bz2
   xfs-2.4.17-split-misc.bz2
   xfs-2.4.17-split-acl-extattr.bz2
(apply in that order)

there's one new change relative to the old one in page_buf_locking.c
that seems to be a bug upstream. i've reported this to them already.
