Subject: [PATCH v16 00/10] unwind_user: Deferred unwinding infrastructure
Date: Tue, 29 Jul 2025 14:23:04 -0400 [thread overview]
Message-ID: <20250729182304.965835871@kernel.org> (raw)
Jen Remus suggested some updates from v15:
https://lore.kernel.org/linux-trace-kernel/20250725185512.673587297@kernel.org/
Those were:
- Make fp_frame into a constant
- Removed useless initializing ra variable to zero

unwind/core
Head SHA1: cf079f0176cc16e937f0fd868f0ec2d649ad53dd
Josh Poimboeuf (3):
unwind_user: Add user space unwinding API with frame pointer support
unwind_user/deferred: Add unwind cache
unwind_user/deferred: Add deferred unwinding interface
Steven Rostedt (7):
unwind_user/deferred: Add unwind_user_faultable()
unwind_user/deferred: Make unwind deferral requests NMI-safe
unwind deferred: Use bitmask to determine which callbacks to call
unwind deferred: Add unwind_completed mask to stop spurious callbacks
unwind: Add USED bit to only have one conditional on way back to user space
unwind deferred: Use SRCU unwind_deferred_task_work()
unwind: Finish up unwind when a task exits
