2002 (change "Replace BKL for chain locking with sysvfs-private rwlock") the sysv filesystem was doing IO under a rwlock in its get_block() function (yes, a non-sleepable lock hold over a function used to read inode metadata for all reads and writes). Nobody noticed until syzbot in 2023 [1]. This shows nobody is using the filesystem. Just drop it.
