Subject: [PATCH] kdbus: avoid the use of struct timespec
|
|
|
|
I did a routine check for new users of 'timespec', which we are trying to remove
|
|
from the kernel in order to survive y2038. kdbus came up and looks particularly
|
|
trivial to clean up.
|
|
|
|
This changes the three ktime_get_ts() variants used in kdbus to ktime_get_ns(),
|
|
which aside from removing timespec also simplifies the code and makes it
|
|
slightly more efficient by avoiding a two-way conversion.
