Description Oliver Henshaw 2015-08-06 15:51:03 UTC
Description of problem:

strace prints st_Xtime fields in stat-like system calls, i.e. with a resolution of a second. This is even when the platform and the file system offer nanosecond resolutions timestamps.

Version-Release number of selected component (if applicable):

strace-4.10-2.fc21.x86_64

How reproducible:

Expected results:

The strace shows nanosecond resolution times, using the Xtim timespec fields.
