With those changes GCC9 fails to analyze arch_futex_atomic_op_inuser() correctly and emits a 'maybe unitialized' warning. While we usually ignore compiler stupidity the conditional store is pointless anyway because the correct case has to store. For the fault case the extra store does no harm. -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEQp8+kY+LLUocC4bMphj1TA10mKEFAl635IgTHHRnbHhAbGlu dXRyb25peC5kZQAKCRCmGPVMDXSYoTQkEAChNFCVLyCNihKNDar4h0LhuChYSVow CRpnLFKTrxWpUemHYgOQM8FBFRjvVK3o3yhmp7qyWc1LnM4iYuGleP+FhfL5F1mk t0ANUMFAZOomy4348XXeVR/bq7RFpKrD68tsl0u3nC+NzykN4kCt3n8qN0CendbH +j9ILi2eNEbSIarC4gH228UuN0YIY5nC9ftW9oHJ+c/Z23X9RXstXhiH1TB9w99E 97G96WOdWjA+z7KzMF1REi/goJGxeZh0GQdz4iuR6vBNd4iR2V9hT3DqklUnSZPp +XGvaWaUH7yVa0etUdCtlBwmZ7Xq3h/N381khq9m6NfXdS8aZ7OavWyf+3urx7xz 6GtCIlo0QnIyqx5oe1/06zxQNgNAf0JAKIi5IDLFsr8SwfoWoG1Z6RrAYugyZurm 9RganJhVGrTXApi/9NUafhqHv7y9OE5UodRLpnKdnjei+/sE51xaIgx7Tr59Ao8n G3sMZkI/8GV9cQnKrg7qcN7kiJfyofoslnOigwm3hJaTMAn0fK9+Bx5YvJgVlyf2 SmE3saw3408/hhqkVWCW5GL8J+JEh/WDi6FCZ3Fu+L1UHalzqDGKAlhfmVxxDNmt tDbP4AUHbucmcWl98Ms0iKtfSwz1H0kTfkaHS0cvphIfH593S4FDJEiywiKsab7v 8nPUV2Bi6vZHxw== =Va5K -----END PGP SIGNATURE----- Merge tag 'locking-urgent-2020-05-10' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull locking fix from Thomas Gleixner: "A single fix for the fallout of the recent futex uacess rework.

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.
