Pull driver core and debugfs updates from Greg KH: "Here is the "big" driver core and debugfs changes for 5.3-rc1 It's a lot of different patches, all across the tree due to some api changes and lots of debugfs cleanups. Other than the debugfs cleanups, in this set of changes we have: - bus iteration function cleanups - scripts/get_abi.pl tool to display and parse Documentation/ABI entries in a simple way - cleanups to Documenatation/ABI/ entries to make them parse easier due to typos and other minor things - default_attrs use for some ktype users - driver model documentation file conversions to .rst - compressed firmware file loading - deferred probe fixes All of these have been in linux-next for a while, with a bunch of merge issues that Stephen has been patient with me for" * tag 'driver-core-5.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: (102 commits) debugfs: make error message a bit more verbose orangefs: fix build warning from debugfs cleanup patch ubifs: fix build warning after debugfs cleanup patch driver: core: Allow subsystems to continue deferring probe drivers: base: cacheinfo: Ensure cpu hotplug work is done before Intel RDT arch_topology: Remove error messages on out-of-memory conditions lib: notifier-error-inject: no need to check return value of debugfs_create functions swiotlb: no need to check return value of debugfs_create functions ceph: no need to check return value of debugfs_create functions sunrpc: no need to check return value of debugfs_create functions ubifs: no need to check return value of debugfs_create functions orangefs: no need to check return value of debugfs_create functions nfsd: no need to check return value of debugfs_create functions lib: 842: no need to check return value of debugfs_create functions debugfs: provide pr_fmt() macro debugfs: log errors when something goes wrong drivers: s390/cio: Fix compilation warning about const qualifiers drivers: Add generic helper to match by of_node driver_find_device: Unify the match function with class_find_device() bus_find_device: Unify the match callback with class_find_device ...

debugfs: make error message a bit more verbose

2019-07-08T08:44:57Z

When a file/directory is already present in debugfs, and it is attempted to be created again, be more specific about what file/directory is being created and where it is trying to be created to give a bit more help to developers to figure out the problem.

debugfs: log errors when something goes wrong

2019-07-03T14:55:51Z

As it is not recommended that debugfs calls be checked, it was pointed out that major errors should still be logged somewhere so that developers and users have a chance to figure out what went wrong. To help with this, error logging has been added to the debugfs core so that it is not needed to be present in every individual file that calls debugfs.

debugfs: call fsnotify_{unlink,rmdir}() hooks

2019-06-20T12:47:09Z

This will allow generating fsnotify delete events after the fsnotify_nameremove() hook is removed from d_delete(). Cc: Greg Kroah-Hartman Reviewed-by: Greg Kroah-Hartman Signed-off-by: Amir Goldstein Signed-off-by: Jan Kara

debugfs: simplify __debugfs_remove_file()

Move simple_unlink()+d_delete() from __debugfs_remove_file() into caller __debugfs_remove() and rename helper for post remove file to __debugfs_file_removed(). This will simplify adding fsnotify_unlink() hook. Cc: Greg Kroah-Hartman Reviewed-by: Greg Kroah-Hartman Signed-off-by: Amir Goldstein Signed-off-by: Jan Kara

Pull misc dcache updates from Al Viro: "Most of this pile is putting name length into struct name_snapshot and making use of it. The beginning of this series ("ovl_lookup_real_one(): don't bother with strlen()") ought to have been split in two (separate switch of name_snapshot to struct qstr from overlayfs reaping the trivial benefits of that), but I wanted to avoid a rebase - by the time I'd spotted that it was (a) in -next and (b) close to 5.1-final ;-/" * 'work.dcache' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: audit_compare_dname_path(): switch to const struct qstr * audit_update_watch(): switch to const struct qstr * inotify_handle_event(): don't bother with strlen() fsnotify: switch send_to_group() and ->handle_event to const struct qstr * fsnotify(): switch to passing const struct qstr * for file_name switch fsnotify_move() to passing const struct qstr * for old_name ovl_lookup_real_one(): don't bother with strlen() sysv: bury the broken "quietly truncate the long filenames" logics nsfs: unobfuscate unexport d_alloc_pseudo()

switch fsnotify_move() to passing const struct qstr * for old_name

2019-04-26T17:22:05Z

note that in the second (RENAME_EXCHANGE) call of fsnotify_move() in vfs_rename() the old_dentry->d_name is guaranteed to be unchanged throughout the evaluation of fsnotify_move() (by the fact that the parent directory is locked exclusive), so we don't need to fetch old_dentry->d_name.name in the caller.
