From 3752466b6bf04868296ac6bc27ea1765008636d8 Mon Sep 17 00:00:00 2001 From: Ben Hutchings Date: Thu, 25 May 2017 12:58:31 +0000 Subject: tools/lib/lockdep: Fix undefined symbol prandom_u32 __lock_pin_lock() now calls prandom_u32() which is not defined in liblockdep. __lock_pin_lock() and its caller lock_pin_lock() are dead code in liblockdep, but we still need to provide a definition of prandom_u32() in case lazy binding is disabled.

That should have resulted in a compiler error, but didn't because: - the check uses ARRAY_SIZE(), which isn't yet defined in liblockdep so is assumed to be an (undeclared) function - putting a function call inside a BUILD_BUG_ON() expression quietly turns it into some nonsense involving a variable-length array It did produce a compiler warning, but I didn't notice because liblockdep already produces too many warnings if -Wall is enabled (which I'll fix shortly). Even before that commit, which reduced lock_chain::depth from 8 bits to 6, MAX_LOCK_DEPTH was too large.
