This update replaces the remaining tasklet usage in the FireWire subsystem with workqueue for asynchronous packet transmission. With this change, tasklets are now fully eliminated from the subsystem. Asynchronous packet transmission is used for serial bus topology management as well as for the operation of the SBP-2 protocol driver (firewire-sbp2). To ensure reliability during low-memory conditions, the associated workqueue is created with the WQ_MEM_RECLAIM flag, allowing it to participate in memory reclaim paths. Other attributes are aligned with those used for isochronous packet handling, which was migrated to workqueues in v6.12. The workqueues are sleepable and support preemptible work items, making them more suitable for real-time workloads that benefit from timely task preemption at the system level. There remains an issue where 'schedule()' may be called within an RCU read-side critical section, due to a direct replacement of 'tasklet_disable_in_atomic()' with 'disable_work_sync()'. A proposed fix for this has been posted[1], and is currently under review and testing. It is expected to be sent upstream later.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
