Description Alasdair Kergon 2012-04-20 19:14:45 UTC 
Allow userspace to hold the root of an LV metadata tree, which guarantees the kernel will not remove any of the metadata in that tree until userspace releases the hold.
Comment 1 RHEL Program Management 2012-07-10 08:25:36 UTC 
This request was not resolved in time for the current release.
Red Hat invites you to ask your support representative to
propose this request, if still desired, for consideration in
the next release of Red Hat Enterprise Linux.
Comment 2 RHEL Program Management 2012-07-10 23:36:35 UTC 
This request was erroneously removed from consideration in Red Hat Enterprise Linux 6.4, which is currently under development.  This request will be evaluated for inclusion in Red Hat Enterprise Linux 6.4.
Comment 3 Alasdair Kergon 2012-07-30 19:33:09 UTC 
upstream commit cc8394d86f045b86ff303d3c9e4ce47d97148951
dm thin: provide userspace access to pool metadata
