Thank you!
Hey Linus, /* Summary */ Features: - Support caching symlink lengths in inodes. The size is stored in a new union utilizing the same space as i_devices, thus avoiding growing the struct or taking up any more space. When utilized it dodges strlen() in vfs_readlink(), giving about 1.5% speed up when issuing readlink on /initrd.img on ext4. - Add RWF_DONTCACHE iocb and FOP_DONTCACHE file_operations flag. If a file system supports uncached buffered IO, it may set FOP_DONTCACHE and enable support for RWF_DONTCACHE. 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 52ac39e5db5148f7 ("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. /* Testing */ gcc version 14.2.0 (Debian 14.2.0-6) Debian clang version 16.0.6 (27+b1) No build failures or warnings were observed. /* Conflicts */ Merge conflicts with mainline ============================= No known conflicts.
