In a few places in sequencer core, we temporarily unlock / re-lock the pool spin lock while waiting for the allocation in the blocking mode. There spin_unlock_irq() / spin_lock_irq() pairs are called while initially spin_lock_irqsave() is used (and spin_lock_irqrestore() at the end of the function again). This is likely OK for now, but it's a bit confusing and error-prone. This patch replaces these temporary relocking lines with the irqsave variant to make the lock/unlock sequence more consistently.

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 Restructured Text 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.
