If RWF_DONTCACHE is attempted without the file system supporting it, it'll get errored with -EOPNOTSUPP - Enable VBOXGUEST and VBOXSF_FS on ARM64 Now that VirtualBox is able to run as a host on arm64 (e.g. the Apple M3 processors) we can enable VBOXSF_FS (and in turn VBOXGUEST) for this architecture. Tested with various runs of bonnie++ and dbench on an Apple MacBook Pro with the latest Virtualbox 7.1.4 r165100 installed Cleanups: - Delay sysctl_nr_open check in expand_files() - Use kernel-doc includes in fiemap docbook - Use page->private instead of page->index in watch_queue - Use a consume fence in mnt_idmap() as it's heavily used in link_path_walk() - Replace magic number 7 with ARRAY_SIZE() in fc_log - Sort out a stale comment about races between fd alloc and dup2() - Fix return type of do_mount() from long to int - Various cosmetic cleanups for the lockref code Fixes: - Annotate spinning as unlikely() in __read_seqcount_begin The annotation already used to be there, but got lost in commit 52ac39e5db ("seqlock: seqcount_t: Implement all read APIs as statement expressions") - Fix proc_handler for sysctl_nr_open - Flush delayed work in delayed fput() - Fix grammar and spelling in propagate_umount() - Fix ESP not readable during coredump In /proc/PID/stat, there is the kstkesp field which is the stack pointer of a thread. While the thread is active, this field reads zero. But during a coredump, it should have a valid value However, at the moment, kstkesp is zero even during coredump - Don't wake up the writer if the pipe is still full - Fix unbalanced user_access_end() in select code" * tag 'vfs-6.14-rc1.misc' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: (28 commits) gfs2: use lockref_init for qd_lockref erofs: use lockref_init for pcl->lockref dcache: use lockref_init for d_lockref lockref: add a lockref_init helper lockref: drop superfluous externs lockref: use bool for false/true returns lockref: improve the lockref_get_not_zero description lockref: remove lockref_put_not_zero fs: Fix return type of do_mount() from long to int select: Fix unbalanced user_access_end() vbox: Enable VBOXGUEST and VBOXSF_FS on ARM64 pipe_read: don't wake up the writer if the pipe is still full selftests: coredump: Add stackdump test fs/proc: do_task_stat: Fix ESP not readable during coredump fs: add RWF_DONTCACHE iocb and FOP_DONTCACHE file_operations flag fs: sort out a stale comment about races between fd alloc and dup2 fs: Fix grammar and spelling in propagate_umount() fs: fc_log replace magic number 7 with ARRAY_SIZE() fs: use a consume fence in mnt_idmap() file: flush delayed work in delayed fput() ...		2025-01-20 09:40:49 -08:00
