Change the cases in show_floppy that print -fd_timer.work.func and fd_timeout.work.func to use the %pf format -specifier, which will print the symbol name, like what is done for the -other function pointers printed by show_floppy. No longer output the -value of cont. The variable cont is a pointer that can hold the -address of kernel global variables. - -Signed-off-by: Brian Belleville <bbellevi@uci.edu> ---- - drivers/block/floppy.c | 5 ++--- - 1 file changed, 2 insertions(+), 3 deletions(-) - -diff --git a/drivers/block/floppy.c b/drivers/block/floppy.c -index eae484acfbbc..e29d4174ea2c 100644 ---- a/drivers/block/floppy.c -+++ b/drivers/block/floppy.c -@@ -1819,15 +1819,14 @@ static void show_floppy(void) - if (work_pending(&floppy_work)) - pr_info("floppy_work.func=%pf\n", floppy_work.func); - if (delayed_work_pending(&fd_timer)) -- pr_info("delayed work.function=%p expires=%ld\n", -+ pr_info("delayed work.function=%pf expires=%ld\n", - fd_timer.work.func, - fd_timer.timer.expires - jiffies); - if (delayed_work_pending(&fd_timeout)) -- pr_info("timer_function=%p expires=%ld\n", -+ pr_info("timer_function=%pf expires=%ld\n", - fd_timeout.work.func, - fd_timeout.timer.expires - jiffies); - -- pr_info("cont=%p\n", cont); - pr_info("current_req=%p\n", current_req); - pr_info("command_status=%d\n", command_status); - pr_info("\n"); --- -2.16.2 - |
