Subject[PATCH 00/16] generic hashtable implementation
Date
There are quite a few places in the kernel which implement a hashtable
in a very similar way. Instead of having implementations of a hashtable
all over the kernel, we can re-use the code.

New changes since the RFC:

- Addressed last comments about previous patches.
- RCU support.
- Simplified the case where the hashtable is allocated statically, which is
the common case.
- A lot more places converted to use the new hashtable.


Sasha Levin (16):
hashtable: introduce a small and naive hashtable
user_ns: use new hashtable implementation
mm,ksm: use new hashtable implementation
workqueue: use new hashtable implementation
mm/huge_memory: use new hashtable implementation
tracepoint: use new hashtable implementation
net,9p: use new hashtable implementation
block,elevator: use new hashtable implementation
SUNRPC/cache: use new hashtable implementation
dlm: use new hashtable implementation
net,l2tp: use new hashtable implementation
dm: use new hashtable implementation
lockd: use new hashtable implementation
net,rds: use new hashtable implementation
openvswitch: use new hashtable implementation
tracing output: use new hashtable implementation
