[LTP] [PATCH 3/3] inotify06: kernel version check

[Dejan Jovicevic]

For test inotify06, kernels prior to 4.2 have a race when inode
is being deleted while inotify group watching that inode is being
torn down. When the race is hit, the kernel crashes or loops. So,
added a check to see if the kernel is >= 4.2.0, and if not, the
test breaks with TCONF and an appropriate message.
