parentafs: Make callback processing more efficient. (diff)
afs: Set error flag rather than return error from file status decode
Set a flag in the call struct to indicate an unmarshalling error rather than return and handle an error from the decoding of file statuses. This flag is checked on a successful return from the delivery function. Signed-off-by: David Howells <dhowells@redhat.com>

 * Function: v5t_early_abort
 *
 * Params  : r2 = pt_regs
 *	   : r4 = aborted context pc
 *	   : r5 = aborted context psr
 *
 * Returns : r4 - r11, r13 preserved
 *
 * Purpose : obtain information about current aborted instruction.
 * Note: we read user space.  This means we might cause a data
 * abort here if the I-TLB and D-TLB aren't seeing the same
 * picture.  Unfortunately, this does happen.  We live with it.
