Subject: [PATCH -next] 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".
Fixes: f05499a06fb4 ("writeback: use ino_t for inodes in tracepoints")
