Description Murphy Zhou 2017-01-05 04:43:35 UTC

Description of problem:

Failed to build radix tree test suite in kernel source tree by
linking to EPEL7 userspace-rcu library.

Using upstream git://git.liburcu.org/userspace-rcu.git libs instead
will fix this issue.

EPEL 7 entered end-of-life (EOL) status on 2024-06-30.\n\nEPEL 7 is no longer maintained, which means that it\nwill not receive any further security or bug fix updates.\n As a result we are closing this bug.
