Merge tag 'vfs-6.7.xattr' of gitolite.kernel.org:pub/scm/linux/kernel/git/vfs/vfs
Pull vfs xattr updates from Christian Brauner: "The 's_xattr' field of 'struct super_block' currently requires a mutable table of 'struct xattr_handler' entries (although each handler itself is const). However, no code in vfs actually modifies the tables. This changes the type of 's_xattr' to allow const tables, and modifies existing file systems to move their tables to .rodata. This is desirable because these tables contain entries with function pointers in them; moving them to .rodata makes it considerably less likely to be modified accidentally or maliciously at runtime" * tag 'vfs-6.7.xattr' of gitolite.kernel.org:pub/scm/linux/kernel/git/vfs/vfs: (30 commits) const_structs.checkpatch: add xattr_handler net: move sockfs_xattr_handlers to .rodata shmem: move shmem_xattr_handlers to .rodata overlayfs: move xattr tables to .rodata xfs: move xfs_xattr_handlers to .rodata ubifs: move ubifs_xattr_handlers to .rodata squashfs: move squashfs_xattr_handlers to .rodata smb: move cifs_xattr_handlers to .rodata reiserfs: move reiserfs_xattr_handlers to .rodata orangefs: move orangefs_xattr_handlers to .rodata ocfs2: move ocfs2_xattr_handlers and ocfs2_xattr_handler_map to .rodata ntfs3: move ntfs_xattr_handlers to .rodata nfs: move nfs4_xattr_handlers to .rodata kernfs: move kernfs_xattr_handlers to .rodata jfs: move jfs_xattr_handlers to .rodata jffs2: move jffs2_xattr_handlers to .rodata hfsplus: move hfsplus_xattr_handlers to .rodata hfs: move hfs_xattr_handlers to .rodata gfs2: move gfs2_xattr_handlers_max to .rodata fuse: move fuse_xattr_handlers to .rodata ...
