Subject: [PATCH] tools/lib/lockdep: Rename "trywlock" into "trywrlock"
Git-commit: 7f3c7952d111ac93573fb86f4d5aeff527a07fcc
Patch-mainline: v5.0-rc1
References: bsc#1121973

This patch avoids that the following compiler warning is reported while
compiling the lockdep unit tests:

Include/liblockdep/rwlock.h: In function 'liblockdep_pthread_rwlock_trywlock':
include/liblockdep/rwlock.h:66:9: warning: implicit declaration of function 'pthread_rwlock_trywlock'; did you mean 'pthread_rwlock_trywrlock'? [-Wimplicit-function-declaration]
  return pthread_rwlock_trywlock(&lock->rwlock) == 0 ? 1 : 0;
         ^~~~~~~~~~~~~~~~~~~~~~~
         pthread_rwlock_trywrlock
