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.
