[ale] Kernel Question: unlink?

[linuxhat at mailandnews.com (linuxhat at mailandnews.com)]

OK.  big evil nassssty hairy kernel question for you (I'm doing a semi-hairy
device driver).  I want to do dynamic allocation of the device major number
(by register_chrdev(0...)), then create the device file on the fly.  This is
all well and good until unload time, at which point I want to call unlink().
There's a kernel version of mknod (do_mknod) that links up just fine.... but
there's no unlink with the usual semantics (char *pathname).  I found a
do_unlink in the kernel source, but it's inlined, not exported.  Do I have
to rip that off, or is there another entry point I can use to blow away that
device file when I exit?  Or am I totally barking up the wrong tree?  Or do
I just need to go get a static number for this device and satisfy myself
with that?  (I'd really rather not if I could....)
