Subject: userns: Disassociate user_struct from the user_namespace.
X-Git-Tag: v3.5-rc1~107^2~31
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=7b44ab978b77a91b327058a0f4db7e6fcdb90b92;p=pandora-kernel.git

userns: Disassociate user_struct from the user_namespace.

Modify alloc_uid to take a kuid and make the user hash table global.
Stop holding a reference to the user namespace in struct user_struct.

This simplifies the code and makes the per user accounting not
care about which user namespace a uid happens to appear in.
