Thanks for your feedback Junjiro > - you replaced __getname_gfp(GFP_NOFS) by __get_free_page(GFP_NOFS) > - but you didn't replace __putname() by free_page() > then it is a problem.
I just tried replacing __putname() with free_page() but the panic continues (appended at the end of this email). > I'd suggest you to > - replace __getname_gfp(GFP_NOFS) by kmem_cache_alloc(names_cachep, GFP_NOFS) > - and leave __putname() as it is Would you send me a diff on how to achieve this? Or some git commit where you have made this change in aufs? [ 20.697232] kernel BUG at mm/slab.c:535!
