[PATCH] shpchp - bugfix: add missing serialization
Current shpchp driver might cause system panic because of lack of
serialization. It can be reproduced very easily by the following
operation.
# cd /sys/bus/pci/slots/<slot#>
# while true; do echo 0 > power ; echo 1 > power ; done &
# while true; do echo 0 > power ; echo 1 > power ; done &
This patch fixes this issue by changing shpchp to get appropreate
semaphore for hot-plug operation.
