Bug Fix: block: Improve stability of SD cards in Microsoft Surface GO 2 and
possibly other devices.
The commit 65a558f66c308
block: Improve performance for BLK_MQ_F_BLOCKING drivers
basically made the use of SD cards in my Microsoft Surface GO 2 impossible.
The cards do stop functioning after about 15 minutes. Mostly at io intensive
tasks.
As outlined in https://bugzilla.kernel.org/show_bug.cgi?id=218821
i bisected the problem that yielded an unstable operation of the cardreader
on my Surface GO 2.
I successfully reversed the commit 65a558f66c308 in 6.12.16 using
the attached patch. As I suppose the bug introduced with this commit might
hit other users of sd-cards in similar hardware I suggest this commit shall
be reversed, even if the improved performance might be gone.
