Previous work reduced it to 1816 lines. This series further reduces it to 1677 lines by moving various definitions to appropriate headers: - Block I/O flags (REQ_OP_*, REQ_SYNC, etc.) to linux/blk_types.h - Block device flags (BLK_OPEN_*) to linux/blkdev.h - Memory allocation flags (__GFP_*, SLAB_*) to linux/slab.h - Scheduler stubs to linux/sched.h - Process flags (PF_MEMALLOC*) to linux/sched.h - System state definitions to linux/kernel.h - Quota format constants to linux/quotaops.h - STATX flags and struct kstat to linux/stat.h - Timer definitions to new linux/hrtimer.h - Inode mutex classes to linux/fs.h - Various other small moves This improves code organisation by placing definitions in headers matching Linux kernel structure, making the codebase easier to maintain and understand.
