Petersen" , Martin Wilck , Christoph Hellwig , Sreekanth Reddy , "Linux regression tracking (Thorsten Leemhuis)" Subject: Please apply commit 06e472acf964 ("scsi: mpt3sas: Remove usage of dma_get_required_mask() API") to stable series Message-ID: MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Precedence: bulk List-ID: X-Mailing-List: stable@vger.kernel.org Dear stable maintainers, Please backport the aboove commit to the stable series. Note, though as a first step it just applies cleanly to 6.1.y. Due to 9df650963bf6 ("scsi: mpt3sas: Don't change DMA mask while reallocating pools") it does not apply cleanly to earlier series. For context: There were several reports in Debian about regression in 5.10.y already: https://bugs.debian.org/1022268 https://bugs.debian.org/1023183 https://bugs.debian.org/1025747 https://bugs.debian.org/1022126 https://lore.kernel.org/linux-scsi/Y1JkuKTjVYrOWbvm@eldamar.lan/ is the initial reporting to upstream and later on brought as well to the regression list: https://lore.kernel.org/regressions/754b030c-ba14-167c-e2d0-2f4f5bf55e99@leemhuis.info/ Thorsten suggested to first get the patch applied at least in 6.1.y but for further steps down we need help. Sreekanth and Martin is this still on your radar? Help with getting this back to 5.10.y would be welcome, and I'm sure with a tentative patch I can get some of the reporting users to report a Tested-by. While people are "unhappy" why it is not fixed yet in Debian, I'm not willing to diverge and appy a patch which is not approved and aimed to go upstream into the respective stable series. But I have too less knowledge here to see which is the correct change to apply to back to 5.10.y alone in case we need to diverge, as 9df650963bf6 picking as well is not an option. Input from you experts on that would be more the appreciated. Regards, Salvatore
