Prepare nfs/sunrpc stack to use multiple instances of rpc_pipefs.
Only for client for now.
It's step forwart to get nfs work from container.
Changelog:
v3:
- rebase to the current Linus' tree (52cfd503ad)
- rework get_rpc_pipefs() once again;
- solve problem with rmmod sunrpc moudle;
- free dns cache on killing rpc_pipefs superblock.
v2:
- one of rpc_create() calls was missed initially, fixed;
- change logic for get_rpc_pipefs(NULL);
- export get_rpc_pipefs() to be able to use from modules (tnx J. Bruce Field);
- change "From:" and "Signed-off-by:" addresses.
v1:
- initial revision of the patchset.
