In my case, this is only needed to simplify debugging of some issues.
'prlctl --device-add hdd <...>' adds a ploop device anyway, it seems.

This patch is for vzkernel from beta3 (that is, 3.10.0-229.7.2.*).
This should help debugging the situations when alloc_vfsmnt() fails.
Rate-limiting is used to avoid the flood of such messages if the mount
limit is hit often.

Hi,
The following patches are needed to fix a problem in ve_mount_allowed
(https://jira.sw.ru/browse/PSBM-42825) and to make debugging of such
issues a bit easier.
The first patch fixes signed/unsigned mismatch in ve_mount_allowed()
that lead to problems. The second one makes sure a message is
, the
kernel will be tainted with TAINT_FORCED_MODULE anyway because the
signature verification will fail. So it will be clearly visible in the
kernel log what is going on.

ends with "cannot allocate memory" and makes no harm.
I did not test !CONFIG_VE case though.

and another VE unmounts it
seem to be of no concern. If so, it is OK not to alter struct mount:
the mount counter for a VE may become unbalanced but this is
acceptable here.

will address this in v.3 of the patch. Thanks!

It is possible for a container to create lots of mount points, which may
make operations with them slower. As some

hopefully it will

less time spent to rework. And we currently really don't need it to be

Let us limit the maximum number of mount points a VE may create. The
limit can be customized via /proc/sys/fs/ve-mount-nr knob.
