I think that's ok with the Coda directories, if not it's really easy to
fix in userland for us. Assume it.
ObCODA: do you have any sort of alignment for cached directories? It would be
ideal if you could guarantee that no entry crosses 4K-boundary in caching
file...
The kernel lock is released the moment the process is put asleep in the
upcall. Keep that in mind.

Hi Stephen,
I have some trouble with using brw_kiovec when the vector contains more
than one kiobuf.
Suppose we pass in an array of 2 kiobufs, each for one page.
It seems to me that the invocation of do_kio in the inner (block) loop
will not happen, neither for iovec[0], nor for iovec[1],
Hi,
A friend lost her partition table...
Is there a scanning tool that can restore it?
Thanks!

GFS gets it right, but solely by the grace that the VFS is not yet fully
threaded, and they have to do the O_EXCL tests twice, once in the VFS
while holding a readlock and then in GFS with a write lock. In
d_revalidate they take a readlock and validate it is still good and

Hi Al,
I agree with your reply and kept thinking more about this. We concluded
that lookup_dentry is _the_ point where passing a flag to the FS makes a
lot of sense if the file system maintains locks - and the flags you
suggest are better than my suggestions.

Let's just take one step back.
Al has successfully pointed out that one should not expect too much in
terms of security improvements for my hardlink suggestion.
Al additionally gave two reasons, totally unrelated to the security
issues, not to implement the link semantics as I suggested:
Hi
I wondered if someone could explain what is happening in
generic_file_read:
More generically, I'd like to understand how in a file system I can
"get" a page and use it to copy date into/out of it. How do I then put
the page away?
There seem to be several patterns, but I can't figure them
