Message-ID: <010701a1a0bf2c14-134ed21a-5472-42f2-acff-680efbee350a-000000@eu-central-1.amazonses.com> (raw)
In-Reply-To: <20261103-ovl-use-orig-ve-v3-3-add042cdd087@virtuozzo.com>
> We may have a case, when VE is dead, but there are some users of it,
> overlayfs superblock for example.
>
> This user may want to use VE creds, so we need to keep ve->init_cred alive.
> Drop creds in ve_destroy. We need to drop ve_nsproxy early because
> ploop waits for refcount going to zero, dropping ve_nsproxy in destroy
> causes CT suspend/resume hangs.
