2021-02-09serial: core: Remove BUG_ON(in_interrupt()) checkAhmed S. Darwish
The usage of in_interrupt() in drivers is phased out for various reasons. In both exported functions where BUG_ON(in_interrupt()) is invoked, there is a mutex_lock() afterwards. mutex_lock() contains a might_sleep() which will already trigger a stack trace if the target functions is called from atomic context. Remove the BUG_ON() and add a "Context: " in the kernel-doc instead. Signed-off-by: Ahmed S.

2021-02-09vt_ioctl: Remove in_interrupt() checkAhmed S. Darwish
reset_vc() uses a "!in_interrupt()" conditional before resetting the palettes, which is a blocking operation. Since commit 8b6312f4dcc1e ("[PATCH] vt: refactor console SAK processing") all calls are invoked from a workqueue process context, with the blocking console lock always acquired.

2021-02-09irqchip/loongson-pch-msi: Use bitmap_zalloc() to allocate bitmapHuacai Chen
Currently we use bitmap_alloc() to allocate msi bitmap which should be initialized with zero. This is obviously wrong but it works because msi can fallback to legacy interrupt mode.

2021-02-09usb: dwc3: gadget: Fix dep->interval for fullspeed interruptThinh Nguyen
The dep->interval captures the number of frames/microframes per interval from bInterval. Fullspeed interrupt endpoint bInterval is the number of frames per interval and not 2^(bInterval - 1).

Multiple structures in the carl9170 driver have alignment impossible alignment constraints that gcc warns about when building with 'make W=1': drivers/net/wireless/ath/carl9170/fwcmd.h:243:2: warning: alignment 1 of 'union <anonymous>' is less than 4 [-Wpacked-not-aligned] drivers/net/wireless/ath/carl9170/wlan.h:373:1: warning: alignment 1 of 'struct ar9170_rx_frame_single' is less than 2 [-Wpacked-not-aligned] In the carl9170_cmd structure, multiple members that have an explicit alignment requirement of four bytes are added into a union with explicit byte alignment, but this in turn is part of a structure that also has four-byte alignment. In the wlan.h header, multiple structures contain a ieee80211_hdr member that is required to be two-byte aligned to avoid alignmnet faults when processing network headers, but all members are forced to be byte-aligned using the __packed tag at the end of the struct definition. In both cases, leaving out the packing does not change the internal layout of the structure but changes the alignment constraint of the structure itself. Change all affected structures to only apply packing where it does not violate the alignment requirement of the contained structure.

2021-02-09btrfs: zoned: deal with holes writing out tree-log pagesNaohiro Aota
Since the zoned filesystem requires sequential write out of metadata, we cannot proceed with a hole in tree-log pages. When such a hole exists, btree_write_cache_pages() will return -EAGAIN. This happens when someone, e.g., a concurrent transaction commit, writes a dirty extent in this tree-log commit. If we are not going to wait for the extents, we can hope the concurrent writing fills the hole for us. So, we can ignore the error in this case and hope the next write will succeed. If we want to wait for them and got the error, we cannot wait for them because it will cause a deadlock. So, let's bail out to a full commit in this case.

2021-02-09btrfs: zoned: reorder log node allocation on zoned filesystemNaohiro Aota
This is the 3/3 patch to enable tree-log on zoned filesystems. The allocation order of nodes of "fs_info->log_root_tree" and nodes of "root->log_root" is not the same as the writing order of them. So, the writing causes unaligned write errors. Reorder the allocation of them by delaying allocation of the root node of "fs_info->log_root_tree," so that the node buffers can go out sequentially to devices.

2021-02-09btrfs: zoned: serialize log transaction on zoned filesystemsNaohiro Aota
This is the 2/3 patch to enable tree-log on zoned filesystems. Since we can start more than one log transactions per subvolume simultaneously, nodes from multiple transactions can be allocated interleaved. Such mixed allocation results in non-sequential writes at the time of a log transaction commit. The nodes of the global log root tree (fs_info->log_root_tree), also have the same problem with mixed allocation. Serializes log transactions by waiting for a committing transaction when someone tries to start a new transaction, to avoid the mixed allocation problem. We must also wait for running log transactions from another subvolume, but there is no easy way to detect which subvolume root is running a log transaction. So, this patch forbids starting a new log transaction when other subvolumes already allocated the global log root tree.

2021-02-09btrfs: zoned: extend zoned allocator to use dedicated tree-log block groupNaohiro Aota
This is the 1/3 patch to enable tree log on zoned filesystems. The tree-log feature does not work on a zoned filesystem as is. Blocks for a tree-log tree are allocated mixed with other metadata blocks and btrfs writes and syncs the tree-log blocks to devices at the time of fsync(), which has a different timing than a global transaction commit. As a result, both writing tree-log blocks and writing other metadata blocks become non-sequential writes that zoned filesystems must avoid. Introduce a dedicated block group for tree-log blocks, so that tree-log blocks and other metadata blocks can be separate write streams. As a result, each write stream can now be written to devices separately. "fs_info->treelog_bg" tracks the dedicated block group and assigns "treelog_bg" on-demand on tree-log block allocation time. This commit extends the zoned block allocator to use the block group.
