Subject: [PATCH v4 4/4] timekeeping: rename getter functions to be consistent and intuitive
Several functions have been added, which all tried to conform to the
function signature of their nearest neighbor, but those neighbors were
also inconsistent with still others. This commit unifies things globally
and adopts a more intuitive adjective ordering. The set of
transformations are:
s/ktime_get_boot_coarse_ns/ktime_get_boottime_coarse_ns/g
s/ktime_get_boot_fast_ns/ktime_get_boottime_fast_ns/g
s/ktime_get_boot_ns/ktime_get_boottime_ns/g
s/ktime_get_tai_coarse_ns/ktime_get_clocktai_coarse_ns/g
s/ktime_get_tai_fast_ns/ktime_get_clocktai_fast_ns/g
s/ktime_get_tai_ns/ktime_get_clocktai_ns/g
s/ktime_get_\([^_]\+\)_coarse/ktime_get_coarse_\1/g
This does not, however, apply:
s/ktime_get_\([^_]\+\)_fast/ktime_get_fast_\1/g
