Why This File Exists

Core operating-system implementation surface: boot, tasks, memory, VFS, syscall-facing interfaces, synchronization, credentials, and isolation.

• Core operating-system implementation surface: boot, tasks, memory, VFS, syscall-facing interfaces, synchronization, credentials, and isolation.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

• linux/types.h
• linux/limits.h
• linux/bug.h
• linux/restart_block.h
• linux/errno.h
• asm/current.h
• linux/bitops.h
• asm/thread_info.h

Detected Declarations

• enum syscall_work_bit
• function set_restart_fn
• function set_ti_thread_flag
• function clear_ti_thread_flag
• function update_ti_thread_flag
• function test_and_set_ti_thread_flag
• function test_and_clear_ti_thread_flag
• function test_ti_thread_flag
• function read_ti_thread_flags
• function tif_test_bit
• function tif_test_bit
• function tif_need_resched
• function arch_within_stack_frames
• function arch_setup_new_exec

• Implementation status: source implementation candidate.

Implementation Notes

• This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
• Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
• Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
