The mv88e6xxx driver expects switches that are configured in single chip addressing mode to have the MDIO address configured as 0. This is due to the switch ADDR pins representing the single chip addressing mode as 0. However depending on the device (e.g. MV88E6*41) the switch does not respond on address 0 or any other address below 16 (the first port address) in single chip addressing mode. This allows for other devices to be on the same shared MDIO bus despite the switch being in single chip addressing mode. When using a switch that works this way it is not possible to configure switch driver as single chip addressing via device tree, along with another MDIO device on the same bus with address 0, as both devices would have the same address of 0 resulting in mdiobus_register_device -EBUSY errors for one of the devices with address 0. In order to support this configuration the switch node can have its MDIO address configured as 16 (the first address that the device responds to). During initialization the driver will treat this address similar to how address 0 is, however because this address is also a valid multi-chip address (in certain switch models, but not all) the driver will configure the SMI in single chip addressing mode and attempt to detect the switch model. If the device is configured in single chip addressing mode this will succeed and the initialization process can continue. If it fails to detect a valid model this is because the switch model register is not a valid register when in multi-chip mode, it will then fall back to the existing SMI initialization process using the MDIO address as the multi-chip mode address. This detection method is safe if the device is in either mode because the single chip addressing mode read is a direct SMI/MDIO read operation and has no side effects compared to the SMI writes required for the multi-chip addressing mode. In order to implement this change, the reset gpio configuration is moved to occur before any SMI initialization. This ensures that the device has the same/correct reset gpio state for both mv88e6xxx_smi_init calls. Signed-off-by:

phy_attach_direct() first calls phy_init_hw() (which restores interrupt settings through ->config_intr()), then calls phy_disable_interrupts(). So if phydev->interrupts was previously set to 1, interrupts are briefly enabled, then disabled, which seems nonsensical. If it was previously set to 0, interrupts are disabled twice, which is equally nonsensical. Deduplicate interrupt disablement. Signed-off-by:

The Time-Specified Departure feature is indeed mutually exclusive with TX IP checksumming in ENETC, but TX checksumming in itself is broken and was removed from this driver in commit 82728b91 ("enetc: Remove Tx checksumming offload code"). The blamed commit declared NETIF_F_HW_CSUM in dev->features to comply with software TSO's expectations, and still did the checksumming in software by calling skb_checksum_help(). So there isn't any restriction for the Time-Specified Departure feature. However, enetc_setup_tc_txtime() doesn't understand that, and blindly looks for NETIF_F_CSUM_MASK. Instead of checking for things which can literally never happen in the current code base, just remove the check and let the driver offload tc-etf qdiscs.

Because nf_sk_lookup_slow*() assume packet headers are in the 'in' direction, use in postrouting is not going to yield a meaningful result.

Commit 00bfe02f ("gfs2: Fix mmap + page fault deadlocks for buffered I/O") changed gfs2_file_read_iter() and gfs2_file_buffered_write() to allow dropping the inode glock while faulting in user buffers. When the lock was dropped, a short result was returned to indicate that the operation was interrupted. As pointed out by Linus (see the link below), this behavior is broken and the operations should always re-acquire the inode glock and resume the operation instead.
