This tunable has been obsolete since 2.6.32, and writes to the
file have been failing and complaining in dmesg since then:
nr_pdflush_threads exported in /proc is scheduled for removal
That was 8 years ago. Remove the file ABI obsolete notice, and
the sysfs file.

mm: prepare for removal of obsolete /proc/sys/vm/nr_pdflush_threads2012-08-01T01:42:40ZWanpeng Liliwp@linux.vnet.ibm.com2012-07-31T23:41:52Zurn:sha1:3965c9ae47d64aadf6f13b6fcd37767b83c0689a
Since per-BDI flusher threads were introduced in 2.6, the pdflush
mechanism is not used any more. But the old interface exported through
/proc/sys/vm/nr_pdflush_threads still exists and is obviously useless.
For back-compatibility, printk warning information and return 2 to notify
the users that the interface is removed.
