[Kernel-packages] [Bug 1825229] [NEW] request to supercede the interim changes for 1815268 with upstream commit 8065a779

2019-04-17 Thread Si-Wei Liu
Public bug reported: The interm patch in LP# 1815268 was positioned as a way of mitigation to the rename race condition as described in that bug. Now, the upstream patch has been accepted and it eliminates the need of the delay. The patch is now in staging tree and should be pulled into mainline
