(If you're reading this patchset for the first time, this patchset is
an effort to improve idr interface. This posting is mostly for
collecting and routing the patches towards -mm. Please follow the

Hello, Andrew.
This patchset is combination of the following three on top of
linux-next as of 20130204 (the one before idr_removal_all() got
included).
[1] [PATCH] idr: fix a subtle bug in idr_get_next()
+ [2] [PATCHSET] idr: deprecate idr_remove_all()
+ [3] [PATCHSET] idr: implement idr_alloc() and convert existing users (w/ all updates)
Please note that we need the idr_get_next() fix before
idr_remove_all() deprecation.
The idr_alloc() part has all the posted updates rolled in and acks
added, and I think it's at least ready for testing. Ah, right, I
skipped deprecation of idr_pre_get() and idr_get_new*() for now. nfs
changes are being routed separately and we can do the deprecation
after after -rc1.
