Comment # 8 on bug 998850 from Peter S�tterlin

Indeed grep for the exact call_site fails.  Here's the cutout of the
interesting region:

ffffffff811901c0 T mempool_resize
ffffffff81190360 T mempool_alloc
ffffffff811904b0 T mempool_destroy

(but that seems quite generic?)

For the others it is
ffffffff8121d680 t path_openat
ffffffff8121ea30 T getname_kernel
ffffffff8121eb30 T putname
ffffffff8121eb80 T getname_flags
ffffffff8121ed60 T getname

ffffffff812297e0 T SyS_getcwd
ffffffff812297e0 T sys_getcwd
ffffffff81229980 T is_subdir
