I've got this BUG a few seconds after I logged in into Gnome desktop :

[partially hand copied BUG]

It's fully reproducible.

/home is mounted with the following options:
   /dev/mapper/vglinux1-lvhome on /home type reiserfs (rw,noatime,nodiratime,user_xattr)

This BUG happened with rc8-mm1 too.
rc6-mm1 works fine.
I didn't try rc7-mm1.

.config attached.

Got it.  I'll try to reproduce.

This sure looks like a result of the reiserfs xattr code beeing
really sucky and passing a NULL vfsmount to dentry_open.

Dave will probably find a bandaid to work around this, but the
right fix is to stop using a file struct here entirely.  If you
look at reiserfs_xattr_set it's not actually used at all except
for passing it to ->prepare_write and ->commit_write which then
don't use it at all.  All that crap should be rewritten to just
pass the dentry around.  Note that all this should not acquire
writer counts on the vfsmount - we have done this already
before calling into the xattr methods.

I'm perplexed as to why a 'struct file' is needed, too.  The 'struct
file' doesn't get used for anything _but_ the dentry, and the functions
to which it is passed (reiserfs_prepate/commit_write()) don't use it.
In fact, some other callers just pass NULL.

This is a completely naive implementation, and I've only tested that it
compiles, but does anybody see a reason we can't just do this?

BTW, do reiserfs developers know that you can put function declarations
in header files?  ;)  4 different .c files have this:

int reiserfs_commit_write(struct page *page, unsigned from, unsigned to);
int reiserfs_prepare_write(struct page *page, unsigned from, unsigned to);

I doubt this will work.  These are also used for the ->prepare_write
and ->commit_write aops, and the method signature definitively wants
a file there, even if it's zero..

Oddly enough, I don't see those functions being used in aops:

const struct address_space_operations reiserfs_address_space_operations = {
        .writepage = reiserfs_writepage,
        .readpage = reiserfs_readpage,
        .readpages = reiserfs_readpages,
        .releasepage = reiserfs_releasepage,
        .invalidatepage = reiserfs_invalidatepage,
        .sync_page = block_sync_page,
        .write_begin = reiserfs_write_begin,
        .write_end = reiserfs_write_end,
        .bmap = reiserfs_aop_bmap,
        .direct_IO = reiserfs_direct_IO,
        .set_page_dirty = reiserfs_set_page_dirty,
};

Plus, reiserfs seems to compile with that patch I just sent.  Sure as
heck surprised me.

That'll be because reiserfs-convert-to-new-aops.patch witched reiserfs over
to ->write_begin() and ->write_end().

So your stuff becomes dependent on Nick's stuff, and Nick's stuff is still
failing on NFS, I think.

Actually, we should rename reiserfs_prepare_write and reiserfs_commit_write
to something else to reduce confusion.  Probably lots of other filesystems
would benefit from the same change, post-Nick's-stuff.

It worked today, it turned out to be a UML bug. Real hardware seemed to
work properly, but will test a bit more tomorrow.

Yeah, I was looking at mainline.

I'd rather avoid the paramater removal for now, that makes it less
entangle, and it's an unrelated cleanup anyway.

Btw, there's more abuse of this sort in reiserfs.  Various other places
in xattr.c call dentry_open directly without the vfsmount aswell.  And
handling of an external journal uses filp_open which is similarly stupid,
it should use open_bdev_excl like xfs or the generic code to open the
main filesystem blockdevice.

And here's a patch to stop the filp abuse in the journal code.  An additional
benefit is that the block device is now properly claimed when opened by
device number.
