6.6-stable review patch. If anyone has any objections, please let me know. ------------------ From: Quinn Tran <qutran@xxxxxxxxxxx> commit 591c1fdf2016d118b8fbde427b796fac13f3f070 upstream. Currently when PCI error is detected, I/O is aborted manually through the ABORT IOCB mechanism which is not guaranteed to succeed. Instead, wait for the OS or system to notify driver to wind down I/O through the pci_error_handlers api. Set eeh_busy flag to pause all traffic and wait for I/O to drain.
