From c15016b7ae1caf77f80ae87a71745368ef651ba6 Mon Sep 17 00:00:00 2001 From: Miklos Szeredi Date: Fri, 22 Oct 2021 17:03:03 +0200 Subject: [PATCH] fuse: simplify local variables holding writeback cache state There are two instances of "bool is_wb = fc->writeback_cache" where the actual use mostly involves checking "is_wb && S_ISREG(inode->i_mode)". Clean up these cases by storing the second condition in the local variable.
