+# CONFIG_XFS_SUPPORT_V4:
+# 
+# The V4 filesystem format lacks certain features that are supported
+# by the V5 format, such as metadata checksumming, strengthened
+# metadata verification, and the ability to store timestamps past the
+# year 2038.  Because of this, the V4 format is deprecated.  All users
+# should upgrade by backing up their files, reformatting, and restoring
+# from the backup.
+# 
+# Administrators and users can detect a V4 filesystem by running
+# xfs_info against a filesystem mountpoint and checking for a string
+# beginning with "crc=".  If the string "crc=0" is found, the
+# filesystem is a V4 filesystem.  If no such string is found, please
+# upgrade xfsprogs to the latest version and try again.
+# 
+# This option will become default N in September 2025.  Support for the
+# V4 format will be removed entirely in September 2030.  Distributors
+# can say N here to withdraw support earlier.
+# 
+# To continue supporting the old V4 format (crc=0), say Y.
+# To close off an attack surface, say N.
+# 
+# Symbol: XFS_SUPPORT_V4 [=y]
+# Type  : bool
