Lower Latency Linux 7.2)
A patch series merged for the Linux 7.2 kernel addresses a race condition that can occur when a container is exiting yielding "VFS: Busy inodes after unmount" messages and a possible user-after-free condition. But the patch series also goes further and delivers a very nice optimization to lower the container unmounting latency for environments with heavy I/O load.
