[gentoo-user] CONFIG_BLK_DEBUG_FS on kernel 6.8.1 considered a Bad Thing.

[gentoo-user] CONFIG_BLK_DEBUG_FS on kernel 6.8.1 considered a Bad Thing.

[Alan Mackenzie]

Hello, Gentoo.

A heads-up for kernel 6.8:

I'm playing with kernel 6.8.1 (direct from Linux).  When I first booted
it, it failed to mount my /boot partition with this error message in
dmesg:

[    5.645341] FAT-fs (nvme0n1p2): bogus number of reserved sectors
[    5.645345] FAT-fs (nvme0n1p2): Can't find a valid FAT filesystem

..  On diffing the 6.7 and 6.8 .config files, I found a new pertinent
item

[*] Block layer debugging information in debugfs

..  When I disabled this and rebuilt the kernel, my /boot mounted without
problem.

I have  CONFIG_BLK_DEBUG_FS=y with no problems (6.8.2 downloaded directly
from kernel.org)
