Sure, I'll update the test condition as you said in the commit message.
FYI, the test is done with 16kb chunk and Pixel 3 (arm64) device.

Since readahead page is charged on memcg too, in theory we don't have to
check this exception now. Before safely remove them all, add a warning
for the unexpected !memcg.

The func is only used in huge_memory.c, defining it in other file with a
CONFIG_TRANSPARENT_HUGEPAGE macro restrict just looks weird.
Let's move it THP. And make it static as Hugh Dickin suggested.

Since the first parameter is only used by head page, it's better to make

lru_lock and page cache xa_lock have no reason with current sequence,
put them together isn't necessary. let's narrow the lru locking, but
left the local_irq_disable to block interrupt re-entry and statistic update.

Currently list of Qualcomm drivers is growing, so put them in to a
proper menu so that it does not mix up with other ASOC configs in menuconfig.
