[PATCH] PCI: sysfs: Change bus_rescan and dev_rescan to rescan

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Kelsey Skunberg <kelsey.skunberg@xxxxxxxxx>

rename device attribute name arguments 'bus_rescan' and 'dev_rescan' to 'rescan'
to avoid breaking userspace applications.

The attribute argument names were changed in the following commits:
8bdfa145f582 ("PCI: sysfs: Define device attributes with DEVICE_ATTR*()")
4e2b79436e4f ("PCI: sysfs: Change DEVICE_ATTR() to DEVICE_ATTR_WO()")

Revert the names used for attributes back to the names used before the above
patches were applied. This also requires to change DEVICE_ATTR_WO() to
DEVICE_ATTR() and __ATTR().

Note when using DEVICE_ATTR() the attribute is automatically named
dev_attr_<name>.attr. To avoid duplicated names between attributes, use
__ATTR() instead of DEVICE_ATTR() to a assign a custom attribute name for
dev_rescan.

change bus_rescan_store() to dev_bus_rescan_store() to complete matching the
names used before the mentioned patches were applied.
