Red Hat's statement on tech preview is here (I sure hope it doesn't
require a login ...) https://access.redhat.com/support/offerings/techpreview

RHEL7.0 GA (released last May) has btrfs kernel code from v3.13.
RHEL7.1 will have btrfs code from around v3.16.
The stability of btrfs in RHEL7 releases depends heavily on the
maturity and stability of upstream btrfs at the time of the release.
IOWS, if btrfs around v3.13 crashed easily; there is nothing magical
in RHEL7.0 to fix that. ;)
