Thanks.
I just added your "Fix memory leak in vc_resize/vc_allocate" patch to my series file.
orphan pointer 0xc6110000 (size 12288): c017480e: <__kmalloc> c024dda4: <vc_resize> c020ed9c: <fbcon_startup> c0251028: <register_con_driver> c02511e0: <take_over_console> c020e21e: <fbcon_takeover> c0212b08: <fbcon_fb_registered> c0212ce1: <fbcon_event_notify> orphan pointer 0xf55b0000 (size 8208): c017480e: <__kmalloc> c0211bb8: <fbcon_set_font> c0251b17: <con_font_set> c0251c7b: <con_font_op> c0249a97: <vt_ioctl> c024432e: <tty_ioctl> c0189fd1: <do_ioctl> c018a269: <vfs_ioctl>
This is interesting. Is it too large? orphan pointer 0xfe09f000 (size 4194304): c016cb9c: <__vmalloc_node> c016cbb2: <__vmalloc> c016cbc7: <vmalloc> fdd3bbe1: <txInit> fdd23b73: <init_jfs_fs> c0149fea: <sys_init_module>
A simple way to reproduce:
while true do sudo mount -o loop -t jfs /home/fs-farm/jfs.img /mnt/fs-farm/jfs/ sudo umount /mnt/fs-farm/jfs/ done
A large collection of false positives :) http://www.stardust.webpages.pl/files/o_bugs/kmemleak-0.9/ml_collection/ml1.tar
