g a heap spraying vector that almost
no-one will ever see for a far more frequent -ENOMEM denial of
service that will be seen on production systems where large xattrs
are used.

use another allocation for ic_bvecs in xlog_alloc_log() (similar
to how we do the separate allocation of the *ic_data buffer that is
mapped into ic_bio at IO time), then none of the code that accesses
ic_bio for IO purposes needs to change and the compiler warnings go
away. That's a much cleaner solution that requires no extra
cognitive load on developers to maintain in correct working order.
