Ok, thanks for the tip. Is this better?
Looks OK. How well tested was it? Nothing calls init_proc_inum_idr().
Maybe all-zeroes happens to work.
Sorry, I tested it all day; it just happens to work :) Olof just
pointed the error out to me, too.
I successfully allocated 152371 proc entries using this.
During testing I made sure that release_inode_number was actually
releasing id's by inserting a call to idr_find before idr_remove, and
using a dummy token for idr_get_new instead of NULL. I can pass those
bits along if you like.
BTW I found the use of idr in kernel/posix-timers.c to be more
consistent with the comments in lib/idr.c so I emulated that. I think
the call to idr_remove in fs/super.c::set_anon_super needs to be holding
unnamed_dev_lock.
Thanks,
Nathan
