X-BeenThere: lustre-devel@lists.lustre.org X-Mailman-Version: 2.1.23 Precedence: list List-Id: "For discussing Lustre software development." List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Cc: Lustre Development List MIME-Version: 1.0 Errors-To: lustre-devel-bounces@lists.lustre.org Sender: "lustre-devel" From: Mr NeilBrown It is Linux policy to avoid #ifdef in C files where convenient - .h files are OK. This patch defines a few inline functions which differ depending on CONFIG_LUSTRE_FS_POSIX_ACL, and removes some #ifdefs from .c files. WC-bug-id: https://jira.whamcloud.com/browse/LU-9679 Lustre-commit: f37e26964a34f ("LU-9679 lustre: remove some "#ifdef CONFIG*" from .c files.")
