As an unintended side-effect, the cio_ignore purge function no longer removes subchannels for devices on the cio_ignore list if no CCW device is attached. This situation occurs when a CCW device is non-operational or unavailable To ensure the same outcome of the purge function as when the current cio_ignore list had been active during boot, update the purge function to remove I/O subchannels without working CCW devices if the associated device number is found on the cio_ignore list.

[PATCH net] net: bonding: fix possible peer notify event loss or dup issue

by Tonghao Zhang

If the send_peer_notif counter and the peer event notify are not synchronized. It may cause problems such as the loss or dup of peer notify event. Before this patch: - If should_notify_peers is true and the lock for send_peer_notif-- fails, peer event may be sent again in next mii_monitor loop, because should_notify_peers is still true. - If should_notify_peers is true and the lock for send_peer_notif-- succeeded, but the lock for peer event fails, the peer event will be lost. This patch locks the RTNL for send_peer_notif, events, and commit simultaneously.

[PATCH v3] i2c: fix reference leak in MP2 PCI device

by Ma Ke

In i2c_amd_probe(), amd_mp2_find_device() utilizes driver_find_next_device() which internally calls driver_find_device() to locate the matching device. driver_find_device() increments the reference count of the found device by calling get_device(), but amd_mp2_find_device() fails to call put_device() to decrement the reference count before returning. This results in a reference count leak of the PCI device each time i2c_amd_probe() is executed, which may prevent the device from being properly released and cause a memory leak. Found by code review. Cc: stable(a)vger.kernel.org Fixes: 529766e0a011 ("i2c: Add drivers for the AMD PCIe MP2 I2C controller") Signed-off-by: Ma Ke <make24(a)iscas.ac.cn> --- Changes in v3: - kept the temporary variable to store pci_get_drvdata() result before releasing the device reference; Changes in v2: - modified the missing initialization in the patch.
