[dm-devel] [PATCH -next] dm stats: Use list_for_each_entry() helper instead of list_for_each() and container_of()

[Jinjie Ruan]

Convert list_for_each() and container_of() to list_for_each_entry()
so that the l list_head pointer and container_of() call are no longer
needed, which can reduce a few lines of code. No functional changed.
