1279 mounts

1279 mounts

[Pete Zaitcev]

I updated my patch that allows to mount unholy numbers of volumes.
The old version was for 2.4.9 and did not apply anymore.
I split the unnamed majors patch and the NFS patch.
Also, CONFIG_ option is gone, because it made the code ugly.

Majors part:
 http://people.redhat.com/zaitcev/linux/linux-2.4.19-pre7-unmaj.diff
NFS part:
 http://people.redhat.com/zaitcev/linux/linux-2.4.19-pre7-nores.diff
Userland for NFS:
 http://people.redhat.com/zaitcev/linux/util-linux-2.11q-nores1.diff

Is anyone actually interested? Random people periodically ask
me for patches, get them and disappear into the void. I hear
nothing good or bad (well, nothing since Trond reviewed it
several months ago, and also someone found a conflict with NFS
server code, since fixed). I am thinking about submitting,
but if users do not ask, why add extra bloat and negotiate
with LANANA...

Heh, one of them would be me! :-D

The requirement for such a large number of mounts does not exist for me
anymore so the patches never went into the production environment for
me.

IMHO, the Linux kernel's inability to handle mounts > 256 mounts is a
deficiency. 

AFAIK, FreeBSD does not have this problem. I would really appreciate it
if these patches made it into the kernel so that I wont be surprised to
realize that Linux cant do more than 256 mounts out of the box the
next time I try it.

Zaitcev, thanx for making those patches available in the first place.
Oh, will you be rolling the user land patches to util-linux to the RedHat
RPMS?

I've got quite a few users here who "need" this functionality and it's 
included in our RH-based custom kernels. Having it as a separate patch 
for 2.4 is no problem, for 2.5 I'm hoping we finally move to 32bit device 
numbers...

Mind, we only ship the unnamed majors part, but not the NFS part.
There is no word from util-linux maintainer about required
changes to mount(8), so I was cautious about doint that.

Sure, I know. In these cases getting the limit from 255 to around 800 is 
enough so the mount patch isn't even needed.
