This patch makes unix_gid_cache cache detail allocated and registered per

Thus with this patch unix_gid_cache contents for network namespace "X" are
controlled from proc file system mount for the same network namespace "X".

I'm confused--this seems half-done. I see that you're creating the gid
caches dynamically, but there's still this static definition:


This static definition is used as a template now.
Have a look at the first path of the series: cache creation routine duplicates incomming cache_detail and initializes net and hash_table fields in freshly created copy.
This copy is the new per-net cache_detail instance.

struct cache_detail unix_gid_cache = {
.owner = THIS_MODULE,
.hash_size = GID_HASHMAX,
- .hash_table = gid_table,
.name = "auth.unix.gid",
.cache_put = unix_gid_put,
.cache_upcall = unix_gid_upcall,

And it looks like unix_gid_lookup is still using this static
unix_gid_cache. Maybe I'm missing something....


Yep, thanks for the catch.
My fault, I've missed this usage.
