Very good job, looking forward to seeing this in the Debian packages :). -- Richard Braun

Yep, definitely :D Samuel

FS_RETRY_MAGICAL is appropriate. But the string itself should more generally describe what it means rather than referring to a specific use case, and should definitely not contain a slash. I'd use just "pid" or perhaps "self-pid" (but it's not "self-tty", so "pid" is probably right). The description should be complete and not leave details to the imagination or presumption: here the omitted detail is the formatting of the number; you can say "in minimal decimal" or you can say "in %u format" to unambiguously mean the same thing. Thanks, Roland

No blank line between the (optional) overview description of the paragraph
and the first (required) file line. Use tabs rather than spaces for the
indentation of the log entry.

More bad indentation.

If you're actually going to have it call itself recursively, then call
__libc_fcntl, not the alias name. But that's not the right thing to do
anyway. Instead, break out the locking cases into a subroutine that you
can call for both versions.

For paranoia's sake, test offsetof matches for each field too.
Why is this a separate file #include'd if it has only the one use?
Just put it directly into fcntl.c instead.
But given the actual implementation in fcntl, I don't think this generic
conversion layer is actually the useful thing to use. You can just make
the new subroutine take the few individual fields that are used as
individual parameters instead of using any struct. You can just do the
EOVERFLOW checks directly before calling the subroutine. Since we don't
actually support F_GETLK, there is no conversion to do in the opposite
direction.
Thanks,

mtab and firmlink loop
Hello, We're having issues with schroot and mtab on exodar. Looking a bit at rpctrace, one can see things like this: /home/srv/chroot/schroot-unpack/youpi/home/srv/chroot/schroot-unpack/youpi/home/srv/chroot/schroot-unpack/youpi/home/srv/chroot/schroot-unpack/youpi/home/srv/chroot/schroot-unpack/youpi/home/srv/chroot/schroot-unpack/youpi/home/srv/chroot/schroot-unpack/youpi/home/srv/chroot/schroot-unpack/youpi/home/schroot/mount/youpi/srv/chroot/schroot-unpack/youpi/servers I have indeed made a bunch of firmlinks: /srv is a firmlink to /home/srv, and /home/srv/chroot/schroot-unpack/youpi/home is a firmlink to /home, thus forming a loop. Can mtab properly cope with this? Samuel
It says HURD 0.6 should be released somewhere in 2013. It's not
Hey guys, I've recently learned about GNU HURD, I'm a linux user. But not a programmer. So I'm sorry I can't help :(. But I do have a question. I was looking up the source code of the HURD on savannah, even though I dont know how to read it, I still like to look at it XD. But something that struck me as peculiar was this http://git.savannah.gnu.org/cgit/hurd/hurd.git/tree/NEWS Notice how it says : 2013-XX-XX Version 0.6 Though 0.6 has never been released. The latest release that Debian HURD uses is 0.5. Why is that? Is there going to be another release this year? Are there a list of improvements or anything that have happened since the last release? I hope this isn't too overwhelming or a waste of time for you.
