Hi!
[ Upstream commit ee050dc83bc326ad5ef8ee93bca344819371e7a5 ]
Replace "depot_save_stack" with "stack_depot_save" in code comments because depot_save_stack() was replaced in commit c0cfc337264c ("lib/stackdepot: Provide functions which operate on plain storage arrays") and removed in commit 56d8f079c51a ("lib/stackdepot: Remove obsolete functions")
This is wrong.

Good catch, I'll go drop this from the stable queues (4.14, 4.9, and 4.19).
Ah, nope, this patch is needed for the "real" patch here, 305e519ce48e ("lib/stackdepot.c: fix global out-of-bounds in stack_slabs")
Hm, it's not that big of a deal, I'll go fix that up by hand...
But that explains why it is included here.
thanks,
