This series moves these stubs to their proper locations in include/linux/, making them available to other subsystems and improving code organisation. The series: - Fixes list_sort() callback signature to match Linux kernel - Moves struct definitions and stubs to appropriate linux/ headers - Adds missing stubs to existing headers (fs.h, blkdev.h, slab.h, etc.) - Creates new stub headers where needed (iomap.h, super_types.h) - Consolidates and sorts the remaining includes This reduces ext4_uboot.h from over 550 lines to around 270 lines. At this point, the work can be considered complete. Simon Glass (33): linux/sort.h: Fix qsort implicit declaration warning list: Add const qualifiers to list_sort callback signature ext4l: Remove redundant header-location comments from ext4_uboot.h ext4l: Move file_operations and inode_operations to linux/fs.h ext4l: Move struct inode and time accessors to linux/fs.h ext4l: Move sb_ functions and SB_ macros to super_types.h ext4l: Move seq_ functions to linux/seq_file.h ext4l: Move inode state accessors to linux/fs.h ext4l: Move generic VFS operations to linux/fs.h ext4l: Move block device operations to linux/blkdev.h ext4l: Move file_ functions to linux/fs.h ext4l: Move fsnotify_sb_error() to linux/fs.h ext4l: Move DEFINE_WAIT to linux/wait.h ext4l: Move filemap_fdatawait_range_keep_errors() to pagemap.h ext4l: Move various stubs to proper linux/ headers ext4l: Consolidate DX_HASH_* into EXT4_UBOOT_NO_EXT4_H block ext4l: Have hash.c include ext4.h directly ext4l: Move inode and filesystem helpers to linux/fs.h ext4l: Move time_is_before_jiffies() to linux/jiffies.h ext4l: Remove duplicate ext4_update_overhead() declaration ext4l: Move xattr helper stubs to linux/xattr.h ext4l: Remove duplicate __ext4_xattr_set_credits() declaration ext4l: Move iomap stubs to linux/iomap.h ext4l: Move setattr stubs to linux/fs.h ext4l: Move finish_open_simple() and ihold() to linux/fs.h ext4l: Move nd_terminate_link() to linux/namei.h ext4l: Move blk_holder_ops to linux/blkdev.h ext4l: Move more stubs to standard Linux headers ext4l: Move WHITEOUT and usercopy stubs to headers ext4l: Move O_SYNC, S_NOQUOTA and kfree_link to headers linux: Add PAGE_SHIFT and PAGE_MASK to linux/compat.h linux: Add DEFINE_RAW_FLEX to linux/overflow.h ext4l: Consolidate and sort includes in ext4_uboot.h .../mach-stm32mp/cmd_stm32prog/stm32prog.c | 9 +- fs/ext4l/ext4_uboot.h | 1476 ++--------------- fs/ext4l/hash.c | 4 +- fs/ext4l/stub.c | 5 + fs/ubifs/gc.c | 19 +- fs/ubifs/replay.c | 6 +- include/linux/blkdev.h | 42 + include/linux/compat.h | 7 + include/linux/dax.h | 23 +- include/linux/fs.h | 336 +++- include/linux/fs/super_types.h | 44 + include/linux/iomap.h | 4 + include/linux/jiffies.h | 3 + include/linux/ktime.h | 9 + include/linux/list_sort.h | 8 +- include/linux/mm_types.h | 3 + include/linux/namei.h | 11 + include/linux/overflow.h | 12 + include/linux/pagemap.h | 2 + include/linux/percpu.h | 1 + include/linux/prefetch.h | 4 +- include/linux/proc_fs.h | 1 + include/linux/rwsem.h | 2 + include/linux/sched/mm.h | 3 + include/linux/seq_file.h | 8 + include/linux/slab.h | 2 + include/linux/sort.h | 2 +- include/linux/wait.h | 3 + include/linux/xattr.h | 4 + lib/efi_loader/efi_memory.c | 7 +- lib/list_sort.c | 12 +- 31 files changed, 716 insertions(+), 1356 deletions(-)
