Original cover letter
---------------------------------------
This RFC patch series addresses suggestion discussed in an earlier
RFC [1]. Since earlier RFC was about SLUB subsystem, and current
changes only involve stackdepot, I am submitting the patches in
a new thread.
The changes of this patch set are as follows:
PATCH-1: Checks validity of a stackdepot handle before proceeding
to access stackdepot slab/objects.
PATCH-2: Adds a helper in stackdepot, to allow users to print
stack entries just by specifying the stackdepot handle.
[1] https://lore.kernel.org/lkml/[email protected]/
--------------------------------------
Changes in v2:
- remove WARN messages
- add declaration of stack_depot_print in stackdepot.h
- make current users, which use stack_depot_fetch + stack_trace_print
to print stack entries, use stack_depot_print
