[PATCH v7 01/11] arm: perf: Remove inlines from arm_pmuv3.c

From: James Clark
Date: Mon Dec 11 2023 - 11:14:09 EST


These are all static and in one compilation unit so the inline has no
effect on the binary. Except if FTRACE is enabled, then 3 functions
which were already not inlined now get the nops added which allows them
to be traced.
