This looks like file->f_inode is NULL, and it's trying to access inode->i_flock.
There's a number of other ones too (that last delayed __fput one, for
example) that might be due to a NULL inode.
And a lot of thre rest are file-handling too, with the BUG_ON() in
__put_cred() when there's something wrong with file->f_cred.
.. but I have no clue how that could happen and why the asm goto
should matter for this.
