From d7d5ed65364ce8d2bcbb93b6c9a7edfcdd706bb0 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Thu, 8 Feb 2024 15:20:53 -0800 Subject: [PATCH] xfs: clean up FS_XFLAG_REALTIME handling in xfs_ioctl_setattr_xflags commit c421df0b19430417a04f68919fc3d1943d20ac04 upstream. Introduce a local boolean variable if FS_XFLAG_REALTIME to make the checks for it more obvious, and de-densify a few of the conditionals using it to make them more readable while at it.
