Thank you!
Hey Linus, /* Summary */ Features: - Support passing NULL along AT_EMPTY_PATH for statx(). NULL paths with any flag value other than AT_EMPTY_PATH go the usual route and end up with -EFAULT to retain compatibility (Rust is abusing calls of the sort to detect availability of statx). This avoids path lookup code, lockref management, memory allocation and in case of NULL path userspace memory access (which can be quite expensive with SMAP on x86_64). - Don't block i_writecount during exec. Remove the deny_write_access() mechanism for executables. - Relax open_by_handle_at() permissions in specific cases where we can prove that the caller had sufficient privileges to open a file. - Switch timespec64 fields in struct inode to discrete integers freeing up 4 bytes. Fixes: - Fix false positive circular locking warning in hfsplus. - Initialize hfs_inode_info after hfs_alloc_inode() in hfs. - Avoid accidental overflows in vfs_fallocate(). - Don't interrupt fallocate with EINTR in tmpfs to avoid constantly restarting shmem_fallocate(). - Add missing quote in comment in fs/readdir. Cleanups: - Don't assign and test in an if statement in mqueue. Move the assignment out of the if statement. - Reflow the logic in may_create_in_sticky(). - Remove the usage of the deprecated ida_simple_xx() API from procfs. - Reject FSCONFIG_CMD_CREATE_EXCL requets that depend on the new mount api early. - Rename variables in copy_tree() to make it easier to understand. - Replace WARN(down_read_trylock, ...) abuse with proper asserts in various places in the VFS. - Get rid of user_path_at_empty() and drop the empty argument from getname_flags(). - Check for error while copying and no path in one branch in getname_flags(). - Avoid redundant smp_mb() for THP handling in do_dentry_open(). - Rename parent_ino to d_parent_ino and make it use RCU. - Remove unused header include in fs/readdir. - Export in_group_capable() helper and switch f2fs and fuse over to it instead of open-coding the logic in both places. /* Testing */ clang: Debian clang version 16.0.6 (26) gcc: (Debian 13.2.0-24) All patches are based on v6.10-rc1 and have been sitting in linux-next. No build failures or warnings were observed. /* Conflicts */ Merge conflicts with other trees ================================ [1]: linux-next: manual merge of the block tree with the vfs-brauner tree https://lore.kernel.org/linux-next/Zn76C70F9QB_Z0bw@sirena.org.uk [2]: linux-next: manual merge of the block tree with the vfs-brauner tree https://lore.kernel.org/linux-next/Zn76HPyBbHbnmGmw@sirena.org.uk The following changes since commit 1613e604df0cd359cf2a7fbd9be7a0bcfacfabd0: Linux 6.10-rc1 (2024-05-26 15:20:12 -0700) are available in the Git repository at: git@gitolite.kernel.org:pub/scm/linux/kernel/git/vfs/vfs tags/vfs-6.11.misc for you to fetch changes up to b80cc4df1124702c600fd43b784e423a30919204: ipc: mqueue: remove assignment from IS_ERR argument (2024-07-09 06:47:40 +0200) Please consider pulling these changes from the signed vfs-6.11.misc tag.
