[GIT PULL] misc updates
From: Christian Brauner
Date: Thu Aug 24 2023 - 10:27:37 EST
Hey Linus,
/* Summary */
This contains the usual miscellaneous features, cleanups, and fixes for
vfs and individual fses.
Features
========
* Block mode changes on symlinks and rectify our broken semantics.
* Report file modifications via fsnotify() for splice.
* Allow specifying an explicit timeout for the "rootwait" kernel command
line option. This allows to timeout and reboot instead of always
waiting indefinitely for the root device to show up.
* Use synchronous fput for the close system call.
Cleanups
========
* Get rid of open-coded lockdep workarounds for async io submitters and
replace it all with a single consolidated helper.
* Simplify epoll allocation helper.
* Convert simple_write_begin and simple_write_end to use a folio.
* Convert page_cache_pipe_buf_confirm() to use a folio.
* Simplify __range_close to avoid pointless locking.
* Disable per-cpu buffer head cache for isolated cpus.
* Port ecryptfs to kmap_local_page() api.
* Remove redundant initialization of pointer buf in pipe code.
* Unexport the d_genocide() function which is only used within core vfs.
* Replace printk(KERN_ERR) and WARN_ON() with WARN().
Fixes
=====
* Fix various kernel-doc issues.
* Fix refcount underflow for eventfds when used as EFD_SEMAPHORE.
* Fix a mainly theoretical issue in devpts.
* Check the return value of __getblk() in reiserfs.
* Fix a racy assert in i_readcount_dec.
* Fix integer conversion issues in various functions.
* Fix LSM security context handling during automounts that prevented NFS
superblock sharing.
/* Testing */
clang: Ubuntu clang version 15.0.7
gcc: (Ubuntu 12.2.0-3ubuntu1) 12.2.0
All patches are based on v6.5-rc1 and have been sitting in linux-next.
No build failures or warnings were observed. All old and new tests in
selftests, and LTP pass without regressions.
/* Conflicts */
At the time of creating this PR no merge conflicts were reported from
linux-next and no merge conflicts showed up doing a test-merge with
current mainline.
The following changes since commit 06c2afb862f9da8dc5efa4b6076a0e48c3fbaaa5:
