The UFS load calculation is based on "total_time" and "busy_time" in a devfreq window. However, the source of time is different for both parameters: "busy_time" is assigned from "jiffies" thus has different accuracy from "total_time" which is assigned from ktime_get(). In addition, the time of window boundary is not exactly the same as the starting busy time in this window if UFS is actually busy in the beginning of the window. A similar accuracy error may also happen for the end of busy time in current window. To guarantee the precision of load calculation, we need to 1. Align time accuracy of both devfreq_dev_status.total_time and devfreq_dev_status.busy_time. For example, use "ktime_get()" directly. 2. Align the following timelines: - The beginning time of devfreq windows - The beginning of busy time in a new window - The end of busy time in the current window Link: https://lore.kernel.org/r/20200611101043.6379-1-stanley.chu@mediatek.com Fixes: a3cd5ec5 ("scsi: ufs: add load based scaling of UFS gear") Reviewed-by:

For UFS 3.1, the normal unit descriptor is 10 bytes larger than the RPMB unit. However, both descriptors share the same desc_idn, to cover both unit descriptors with one length, we choose the normal unit descriptor length by desc_index.

MediaTek UFS clocks are separated to two parts and controlled by different modules: ufs-mediatek and phy-ufs-mediatek. If both Auto-Hibern8 and clk-gating feature are enabled, mphy power control is not balanced thus unbalanced control also happens to the clocks probed by phy-ufs-mediatek module. Fix this issue by: - Promise usage of phy_power_on/off balanced - Remove phy_power_on/off control in suspend/resume vops since both can be handled in setup_clock vops only Link: https://lore.kernel.org/r/20200601104646.15436-5-stanley.chu@mediatek.comReviewed-by:

There is a chance that link enters hibern8 via auto-hibern8 scheme during the clock-gating flow. Clocks shall not be gated if link is still active otherwise host or device may hang. Fix this by returning error code to the caller __ufshcd_setup_clocks() to skip gating clocks there if link is not confirmed in hibern8 state yet.

The SafeSetID LSM uses the security_task_fix_setuid hook to filter set*uid() syscalls according to its configured security policy. In preparation for adding analagous support in the LSM for set*gid() syscalls, we add the requisite hook here. Tested by putting print statements in the security_task_fix_setgid hook and seeing them get hit during kernel boot. Signed-off-by:

This reverts commit a43a67a2. This patch reverts the main part of switching direct io implementation to iomap infrastructure. There's a problem in invalidate page that couldn't be solved as regression in this development cycle. The problem occurs when buffered and direct io are mixed, and the ranges overlap. Although this is not recommended, filesystems implement measures or fallbacks to make it somehow work. In this case, fallback to buffered IO would be an option for btrfs (this already happens when direct io is done on compressed data), but the change would be needed in the iomap code, bringing new semantics to other filesystems. Another problem arises when again the buffered and direct ios are mixed, invalidation fails, then -EIO is set on the mapping and fsync will fail, though there's no real error. There have been discussions how to fix that, but revert seems to be the least intrusive option. Link: https://lore.kernel.org/linux-btrfs/20200528192103.xm45qoxqmkw7i5yl@fiona/Signed-off-by:

On AM65xx MCU CPSW2G NUSS and 66AK2E/L NUSS allmulti setting does not allow unregistered mcast packets to pass. This happens, because ALE VLAN entries on these SoCs do not contain port masks for reg/unreg mcast packets, but instead store indexes of ALE_VLAN_MASK_MUXx_REG registers which intended for store port masks for reg/unreg mcast packets. This path was missed by commit 9d1f6447 ("net: ethernet: ti: ale: fix seeing unreg mcast packets with promisc and allmulti disabled"). Hence, fix it by taking into account ALE type in cpsw_ale_set_allmulti(). Fixes: 9d1f6447 ("net: ethernet: ti: ale: fix seeing unreg mcast packets with promisc and allmulti disabled") Signed-off-by:
