The deprecation will take place in two parts.  Support for mounting V4

filesystems can now be disabled at kernel build time via Kconfig option.

The option will default to yes until September 2025, at which time it

will be changed to default to no.  In September 2030, support will be

removed from the codebase entirely.

These options were changed to default to no in September 2025.  In

September 2030, support will be removed from the codebase entirely.



Note: Distributors may choose to withdraw V4 format support earlier than

the dates listed above.
