Today, driver has a synchronization point while closing the device which synchronizes its slowpath interrupt line. However, that's insufficient as that ISR would schedule the slowpath-tasklet - so even after ISR is over it's possible the handling of the interrupt has not completed. By doing a disable/enable on the taskelt we guarantee that all HW events that should no longer be genereated from that point onward in the flow are truly behind us. Signed-off-by:

Prior to the pstore interface refactoring, the "id" generated during a backend pstore_write() was only retained by the internal pstore inode tracking list. Additionally the "part" was ignored, so EFI would encode this in the id. This corrects the misunderstandings and correctly sets "id" during pstore_write(), and uses "part" directly during pstore_erase(). Reported-by:

Vivien Didelot says: ==================== net: dsa: distribute switch events DSA is by nature the support for a switch fabric, which can be composed of a single, or multiple interconnected Ethernet switch chips. The current DSA core behavior is to identify the slave port targeted by a request (e.g. adding a VLAN entry), and program the switch chip to which it belongs accordingly. This is problematic in a multi-chip environment, since all chips of a fabric must be aware of most configuration changes. Here are some concrete examples in a 3-chip environment: [CPU].................... (mdio) (eth0) | : : : _|_____ _______ _______ [__sw0__]--[__sw1__]--[__sw2__] | | | | | | | | | v v v v v v v v v p1 p2 p3 p4 p5 p6 p7 p8 p9 If you add a VLAN entry on p7, sw2 gets programmed, but frames won't reach the CPU interface in a VLAN filtered setup. sw0 and sw1 also need to be programmed. The same problem comes with MAC addresses (FDB, MDB), or ageing time changes for instance. This patch series uses the notification chain introduced for bridging, to notify not only bridge, but switchdev attributes and objects events to all switch chips of the fabric. An ugly debug message printing the ignored event and switch info in the code handling the switch VLAN events would give us: # bridge vlan add dev p7 vid 42 sw0: ignoring DSA_NOTIFIER_VLAN_ADD for sw2 (prepare phase) sw1: ignoring DSA_NOTIFIER_VLAN_ADD for sw2 (prepare phase) sw0: ignoring DSA_NOTIFIER_VLAN_ADD for sw2 (commit phase) sw1: ignoring DSA_NOTIFIER_VLAN_ADD for sw2 (commit phase) To achieve that, patches 1-8 change the scope of the bridge and switchdev callbacks from the DSA slave device to the generic DSA port, so that the port-wide API can be used later for switch ports not exposed to userspace, such as CPU and DSA links. Patches 9-15 move the DSA port specific functions in a new port.c file. Patches 16-20 introduce new events to notify the fabric about switchdev attributes and objects manipulation. This patch series only adds the plumbing to support a distributed configuration, but for the moment, each switch chip ignores events from other chips of the fabric, to keep the current behavior. The next patch series will add support for cross-chip configuration of bridge ageing time, VLAN and MAC address databases operations, etc. ==================== Tested-by:

This patch keeps the port-wide ageing time handling code in dsa_port_ageing_time, pushes the requested ageing time value in a new switch fabric notification, and moves the switch-wide ageing time handling code in dsa_switch_ageing_time. This has the effect that now not only the switch that the target port belongs to can be programmed, but all switches composing the switch fabric. For the moment, keep the current behavior and ignore other switches. Signed-off-by:

The DSA notifier events and info structure definitions are not meant for DSA drivers and users, but only used internally by the DSA core files. Move them from the public net/dsa.h file to the private dsa_priv.h file. Also use this opportunity to turn the events into an anonymous enum, because we don't care about the values, and this will prevent future conflicts when adding (and sorting) new events.
