From fefb8a2a941338d871e2d83fbd65fbfa068857bd Mon Sep 17 00:00:00 2001 From: Randy Dunlap Date: Wed, 16 Mar 2022 12:20:03 -0700 Subject: virtio_console: eliminate anonymous module_init & module_exit Eliminate anonymous module_init() and module_exit(), which can lead to confusion or ambiguity when reading System.map, crashes/oops/bugs, or an initcall_debug log. Give each of these init and exit functions unique driver-specific names to eliminate the anonymous names. Example 1: (System.map) ffffffff832fc78c t init ffffffff832fc79e t init ffffffff832fc8f8 t init Example 2: (initcall_debug log) calling init+0x0/0x12 @ 1 initcall init+0x0/0x12 returned 0 after 15 usecs calling init+0x0/0x60 @ 1 initcall init+0x0/0x60 returned 0 after 2 usecs calling init+0x0/0x9a @ 1 initcall init+0x0/0x9a returned 0 after 74 usecs Signed-off-by: Randy Dunlap Reviewed-by: Amit Shah Cc: virtualization@lists.linux-foundation.org Cc: Arnd Bergmann Link: https://lore.kernel.org/r/20220316192010.19001-3-rdunlap@infradead.org Signed-off-by: Greg Kroah-Hartman --- drivers/char/virtio_console.c | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) diff --git a/drivers/char/virtio_console.c b/drivers/char/virtio_console.c index 2359889a35a0..36e437d74d2d 100644 --- a/drivers/char/virtio_console.c +++ b/drivers/char/virtio_console.c @@ -2238,7 +2238,7 @@ static struct virtio_driver virtio_rproc_serial = { .remove = virtcons_remove, }; -static int __init init(void) +static int __init virtio_console_init(void) { int err; @@ -2273,7 +2273,7 @@ free: return err; } -static void __exit fini(void) +static void __exit virtio_console_fini(void) { reclaim_dma_bufs(); @@ -2283,8 +2283,8 @@ static void __exit fini(void) class_destroy(pdrvdata.class); debugfs_remove_recursive(pdrvdata.debugfs_dir); } -module_init(init); -module_exit(fini); +module_init(virtio_console_init); +module_exit(virtio_console_fini); MODULE_DESCRIPTION("Virtio console driver"); MODULE_LICENSE("GPL"); -- cgit v1.2.3
