It makes a lot of sense as amd64 code, though:
55 push %rbp 48 89 e5 mov %rsp,%rbp 41 55 push %r13 41 54 push %r12
IOW, it's the first 8 bytes from a fairly sane beginning of some function. So &(inode->i_fop->owner) (and thus inode->i_fop - owner is the first field) is some spot in .text. Would be interesting to find out what function was that from (i.e. what's the value of inode->i_fop); with any luck it might've still been in some register. Could you post objdump of do_dentry_open() from your kernel?
