From: Simon Glass <simon.glass@canonical.com> This series reduces fs/ext4l/ext4_uboot.h from 2584 to 1980 lines (a 23% reduction) by moving definitions to appropriate include/linux/ header files. The ext4l subsystem requires many Linux kernel types and functions. Rather than keeping everything in one large file, this series creates proper stub headers in include/linux/ matching Linux kernel organisation: - ktime.h: Time functions and ktime_t type - rcupdate.h: RCU stubs (single-threaded no-ops) - shrinker.h: Memory-reclaim stubs - mm_types.h: VM stubs (address_space, vm_area_struct) - pagemap.h: Page cache and folio stubs - bio.h: Block I/O stubs - fs_context.h/fs_parser.h: Filesystem context types - dcache.h: Dentry and qstr types - uuid.h: UUID/GUID types - smp.h: SMP memory barriers - refcount.h: Reference counting type - kobject.h: Kobject stubs - xarray.h: XArray stubs - mempool.h: Memory pool stubs - kdev_t.h: Device number macros - fsmap.h: Filesystem map definitions Additionally, cmpxchg(), try_cmpxchg(), and xchg() are moved to asm-generic/atomic.h, and blk_plug is added to linux/blkdev.h. All implementations are appropriate stubs for U-Boot's single-threaded, no-VM, no-page-cache environment. Simon Glass (19): linux: Add ktime.h header with time functions linux: Add rcupdate.h header with RCU stubs linux: Add shrinker.h header with memory-reclaim stubs linux: Add mm_types.h header with VM stubs linux: Add pagemap.h header with folio and page cache stubs linux: Add bio.h header with block I/O stubs linux: Add fs_context.h and fs_parser.h headers linux: Add dcache.h header with dentry stubs linux: Add uuid.h header with UUID/GUID types asm-generic: atomic: Add cmpxchg() macro linux: Add smp.h header with SMP stubs linux: Add refcount.h header with refcount_t type linux: Add kobject.h header with kobject stubs linux: Add xarray.h header with XArray stubs linux: Add mempool.h header with memory pool stubs linux: Add kdev_t.h header with device number macros linux: blkdev: Add blk_plug structure and operations linux: Add fsmap.h header with filesystem map definitions asm-generic: atomic: Add xchg() and try_cmpxchg() macros fs/ext4l/ext4_fscrypt.h | 9 +- fs/ext4l/ext4_uboot.h | 738 ++++------------------------------- include/asm-generic/atomic.h | 55 +++ include/linux/bio.h | 117 ++++++ include/linux/blkdev.h | 25 ++ include/linux/dcache.h | 94 +++++ include/linux/fs_context.h | 154 ++++++++ include/linux/fs_parser.h | 110 ++++++ include/linux/fsmap.h | 46 +++ include/linux/kdev_t.h | 56 +++ include/linux/kobject.h | 34 ++ include/linux/ktime.h | 70 ++++ include/linux/mempool.h | 57 +++ include/linux/mm_types.h | 116 ++++++ include/linux/pagemap.h | 201 ++++++++++ include/linux/rcupdate.h | 54 +++ include/linux/refcount.h | 70 ++++ include/linux/shrinker.h | 83 ++++ include/linux/smp.h | 60 +++ include/linux/uuid.h | 120 ++++++ include/linux/xarray.h | 50 +++ 21 files changed, 1640 insertions(+), 679 deletions(-) create mode 100644 include/linux/bio.h create mode 100644 include/linux/dcache.h create mode 100644 include/linux/fs_context.h create mode 100644 include/linux/fs_parser.h create mode 100644 include/linux/fsmap.h create mode 100644 include/linux/kdev_t.h create mode 100644 include/linux/kobject.h create mode 100644 include/linux/ktime.h create mode 100644 include/linux/mempool.h create mode 100644 include/linux/mm_types.h create mode 100644 include/linux/pagemap.h create mode 100644 include/linux/rcupdate.h create mode 100644 include/linux/refcount.h create mode 100644 include/linux/shrinker.h create mode 100644 include/linux/smp.h create mode 100644 include/linux/uuid.h create mode 100644 include/linux/xarray.h -- 2.43.0 base-commit: 3f7c0f2d98ec4d41d0f15578358219ae2fdf8b88 branch: extr
