2020-03-25arm64: head: Convert install_el2_stub to SYM_INNER_LABELMark Brown
New assembly annotations have recently been introduced which aim to make the way we describe symbols in assembly more consistent. Recently the arm64 assembler was converted to use these but install_el2_stub was missed.

2020-03-25backlight: corgi: Convert to use GPIO descriptorsLinus Walleij
The code in the Corgi backlight driver can be considerably simplified by moving to GPIO descriptors and lookup tables from the board files instead of passing GPIO numbers using the old API.

2020-03-25fanotify: Drop fanotify_event_has_fid()Jan Kara
When some events have directory id and some object id, fanotify_event_has_fid() becomes mostly useless and confusing because we usually need to know which type of file handle the event has. So just drop the function and use fanotify_event_object_fh() instead. Signed-off-by: Jan Kara <jack@suse.cz>
2020-03-25fanotify: prepare to report both parent and child fid'sAmir Goldstein
For some events, we are going to report both child and parent fid's, so pass fsid and file handle as arguments to copy_fid_to_user(), which is going to be called with parent and child file handles.

2020-03-25fanotify: send FAN_DIR_MODIFY event flavor with dir inode and nameAmir Goldstein
Dirent events are going to be supported in two flavors: 1. Directory fid info + mask that includes the specific event types (e.g. FAN_CREATE) and an optional FAN_ONDIR flag. 2. Directory fid info + name + mask that includes only FAN_DIR_MODIFY. To request the second event flavor, user needs to set the event type FAN_DIR_MODIFY in the mark mask. The first flavor is supported since kernel v5.1 for groups initialized with flag FAN_REPORT_FID. It is intended to be used for watching directories in "batch mode" - the watcher is notified when directory is changed and re-scans the directory content in response. This event flavor is stored more compactly in the event queue, so it is optimal for workloads with frequent directory changes. The second event flavor is intended to be used for watching large directories, where the cost of re-scan of the directory on every change is considered too high. The watcher getting the event with the directory fid and entry name is expected to call fstatat(2) to query the content of the entry after the change. Legacy inotify events are reported with name and event mask (e.g. "foo", FAN_CREATE | FAN_ONDIR). That can lead users to the conclusion that there is *currently* an entry "foo" that is a sub-directory, when in fact "foo" may be negative or non-dir by the time user gets the event. To make it clear that the current state of the named entry is unknown, when reporting an event with name info, fanotify obfuscates the specific event types (e.g. create,delete,rename) and uses a common event type - FAN_DIR_MODIFY to describe the change. This should make it harder for users to make wrong assumptions and write buggy filesystem monitors. At this point, name info reporting is not yet implemented, so trying to set FAN_DIR_MODIFY in mark mask will return -EINVAL.

2020-03-25fanotify: divorce fanotify_path_event and fanotify_fid_eventJan Kara
Breakup the union and make them both inherit from abstract fanotify_event. fanotify_path_event, fanotify_fid_event and fanotify_perm_event inherit from fanotify_event. type field in abstract fanotify_event determines the concrete event type. fanotify_path_event, fanotify_fid_event and fanotify_perm_event are allocated from separate memcache pools. Rename fanotify_perm_event casting macro to FANOTIFY_PERM(), so that FANOTIFY_PE() and FANOTIFY_FE() can be used as casting macros to fanotify_path_event and fanotify_fid_event.

2020-03-25fanotify: Store fanotify handles differentlyJan Kara
Currently, struct fanotify_fid groups fsid and file handle and is unioned together with struct path to save space. Also there is fh_type and fh_len directly in struct fanotify_event to avoid padding overhead. In the follwing patches, we will be adding more event types and this packing makes code difficult to follow. So unpack everything and create struct fanotify_fh which groups members logically related to file handle to make code easier to follow. In the following patch we will pack things again differently to make events smaller. Signed-off-by: Jan Kara <jack@suse.cz>
2020-03-25fanotify: Simplify create_fd()Jan Kara

2020-03-24scsi: sd: Fix optimal I/O size for devices that change reported valuesMartin K. Petersen
Some USB bridge devices will return a default set of characteristics during initialization. And then, once an attached drive has spun up, substitute the actual parameters reported by the drive. According to the SCSI spec, the device should return a UNIT ATTENTION in case any reported parameters change. But in this case the change is made silently after a small window where default values are reported. Commit a83da8a4509d ("scsi: sd: Optimal I/O size should be a multiple of physical block size") validated the reported optimal I/O size against the physical block size to overcome problems with devices reporting nonsensical transfer sizes. However, this validation did not account for the fact that aforementioned devices will return default values during a brief window during spin-up. The subsequent change in reported characteristics would invalidate the checking that had previously been performed. Unset a previously configured optimal I/O size should the sanity checking fail on subsequent revalidate attempts.

2020-03-25zonfs: Fix handling of read-only zonesDamien Le Moal
The write pointer of zones in the read-only consition is defined as invalid by the SCSI ZBC and ATA ZAC specifications. It is thus not possible to determine the correct size of a read-only zone file on mount. Fix this by handling read-only zones in the same manner as offline zones by disabling all accesses to the zone (read and write) and initializing the inode size of the read-only zone to 0). For zones found to be in the read-only condition at runtime, only disable write access to the zone and keep the size of the zone file to its last updated value to allow the user to recover previously written data. Also fix zonefs documentation file to reflect this change. Signed-off-by: Damien Le Moal <damien.lemoal@wdc.com> Reviewed-by: Johannes Thumshirn <johannes.thumshirn@wdc.com>

2020-03-24clk: sprd: Add macros for referencing parents without stringsChunyan Zhang
With the new clk parenting code, clk_init_data was expanded to include .parent_hws and .parent_data, for clk drivers to specify parents without name strings of clocks. Also some macros were added for using these two items to reference clock parents. Based on that to expand macros for sprd clocks: - SPRD_*_DATA, take an array of struct clk_parent_data * as its parents which should be a combination of .fw_name (devicetree clock-names), .hw (pointers to a local struct clk_hw). - SPRD_*_HW, take a local struct clk_hw pointer, instead of a string, as its parent. - SPRD_*_FW_NAME, take a string of clock-names decleared in the device tree as the clock parent.
