Fix for the "timer -r" command on Linux 4.10 and later kernels that
|
|
|
7ef056 |
contain commit 2456e855354415bfaeb7badaa14e11b3e02c8466, titled
|
|
|
7ef056 |
"ktime: Get rid of the union". Without the patch, the command fails
|
|
|
7ef056 |
with the error message "timer: invalid structure member offset:
|
|
|
7ef056 |
ktime_t_sec".
