This seems to have broken the use of /proc/bus/usb as a mountpoint. It
always appears empty now, whatever's supposed to be mounted there.

Yes.  Denis and Eric are tossing around competing patches but afaik nobody
is happy with any of them.  Guys, could we get this sorted soonish please?

"Soonish" being rather earlier than 20071227?
'cause it's still throwing a fit for me on 2.6.24-rc6-mm1(!) (plus hotfix),
nothing visible in /proc/bus/usb, thus WLAN driver won't probe
anything.

Patch which restores usual behaviour was merged in 2.6.24-rc5
(3790ee4bd86396558eedd86faac1052cb782e4e1 "proc: remove/Fix proc generic d_revalidate")

Via a kerneltrap.org article (problematic internet setup here currently,
non-C&P text terminal only) I could see that this is the patch which
removes the d_revalidate member and the corresponding proc_revalidate_dentry().
And this is the state that my 2.6.24-rc_six_-mm1 tree is in already.
So either it didn't help here or it broke again by some later change or
there's some dumb PEBKAC error here.

so no hotfixes are needed. I just checked with bind mounting / to
/proc/bus/usb -- it works.

OK, I'll try to re-check manual, raw, bare-metal mounting (bind etc.) soonish.

"CONFIG_NETNS" as mentioned in the patch description actually seems
to be "CONFIG_NET_NS", BTW.
(which I DON'T have set at the moment, if this happens to make a difference)

Thanks,

Andreas Mohr
