[Devel] [PATCH CRIU 0/6] Switch user_ns before mount binfmt_misc

[Kirill Tkhai]

After vzkernel commit 1352424aae37 "ms/fs: Add user namespace member to struct super_block"
we have to switch to CT's user_ns before mounting binfmt_misc.

This series simply does that.

Patches [3/6] and [4/6] are taken from upstream criu-dev.
