[Qemu-trivial] [PATCH v2] coroutine: Fix documentation of co_aio_sleep_ns() |
Date: |
Wed, 8 Nov 2017 10:55:19 -0600 |
co_sleep_ns() was removed in commit 0b9caf9b, leaving behind a
stale comment. Update the documentation to match the current
usage of this function.
Suggested-by: Paolo Bonzini <address@hidden>

v2: instead of just blindly cribbing from Paolo's email, try to incorporate
the feedback given on the wording
