Revision a6cf4e0fe3e740ed7af39fdda721e1ac12247dd3 authored by Uladzislau Rezki (Sony) on 17 May 2019, 21:31:37 UTC, committed by Linus Torvalds on 18 May 2019, 22:52:26 UTC 
mm/vmap: add DEBUG_AUGMENT_LOWEST_MATCH_CHECK macro
 
This macro adds some debug code to check that vmap allocations are
happened in ascending order.

By default this option is set to 0 and not active.  It requires
recompilation of the kernel to activate it.  Set to 1, compile the
kernel.
