From 40363cf13999ee4fb3b5c1e67fa5e6f0e9da34bd Mon Sep 17 00:00:00 2001 From: Qian Cai Date: Thu, 14 Nov 2019 12:17:41 -0500 Subject: [PATCH] writeback: fix -Wformat compilation warnings The commit f05499a06fb4 ("writeback: use ino_t for inodes in tracepoints") introduced a lot of GCC compilation warnings on s390, In file included from ./include/trace/define_trace.h:102, from ./include/trace/events/writeback.h:904, from fs/fs-writeback.c:82: ./include/trace/events/writeback.h: In function 'trace_raw_output_writeback_page_template': ./include/trace/events/writeback.h:76:12: warning: format '%lu' expects argument of type 'long unsigned int', but argument 4 has type 'ino_t' {aka 'unsigned int'} [-Wformat=] TP_printk("bdi %s: ino=%lu index=%lu", ^~~~~~~~~~~~~~~~~~~~~~~~~~~ ./include/trace/trace_events.h:360:22: note: in definition of macro 'DECLARE_EVENT_CLASS' trace_seq_printf(s, print); \ ^~~~~ ./include/trace/events/writeback.h:76:2: note: in expansion of macro 'TP_printk' TP_printk("bdi %s: ino=%lu index=%lu", ^~~~~~~~~ Fix them by adding necessary casts where ino_t could be either "unsigned int" or "unsigned long".
