Package: src:linux
Version: 6.18.5-1
Severity: normal
X-Debbugs-Cc: 10dmar10@gmail.com

Dear Maintainer,

linux-image-6.18.5+deb14-amd64 seems to be unable to mount existing legacy XFS V4 filesystems
reporting:

XFS (...): Depricated V4 format (crc=0) not supported by kernel.

reason seems to be a missing setting
>  cat /boot/config-6.18.5+deb14-amd64 | grep CONFIG_XFS_SUPPORT_V4
# CONFIG_XFS_SUPPORT_V4 is not set


this setting was recently still enabled:

XFS (sda3): Deprecated V4 format (crc=0) will not be supported after September 2030.

> cat /boot/config-6.17.13+deb14-amd64 | grep CONFIG_XFS_SUPPORT_V4
CONFIG_XFS_SUPPORT_V4=y


while no longer used by default, XFS V4 support is still useful for accessing
legacy XFS V4 file systems as long as kernel supports it.
