commit 720944ea26014a1830f9b44bda13b79e8e7d753b Author: Julien Grall <jgrall@xxxxxxxxxx> AuthorDate: Mon Jan 30 18:28:58 2023 +0000 Commit: Julien Grall <julien@xxxxxxx> CommitDate: Thu Feb 16 21:58:26 2023 +0000 xen/common: rwlock: Constify the parameter of _rw_is{,_write}_locked() The lock is not meant to be modified by _rw_is{,_write}_locked(). So constify it. This is helpful to be able to assert if the lock is taken when the underlying structure is const.
