| |
On BITS_PER_LONG < 64 and !CONFIG_KTIME_SCALAR we get this:
CC kernel/hrtimer.o kernel/hrtimer.c:303: error: redefinition of '__kstrtab_ktime_add_ns' kernel/hrtimer.c:279: error: previous definition of '__kstrtab_ktime_add_ns' was here kernel/hrtimer.c:303: error: redefinition of '__ksymtab_ktime_add_ns' kernel/hrtimer.c:279: error: previous definition of '__ksymtab_ktime_add_ns' was here kernel/hrtimer.c:313: error: redefinition of 'ktime_sub_ns' kernel/hrtimer.c:289: error: previous definition of 'ktime_sub_ns' was here make[1]: *** [kernel/hrtimer.o] Error 1 make: *** [kernel] Error 2
For some reason the ktime_sub_ns() addition was duplicated, and someone forgot to change the name of the ktime_add_ns() symbol export they lifted.
Get it building again.
