Subject: [EXT4 set 2][PATCH 3/5] cleanups: set_jbd2_64bit_feature for >16TB ext4 fs

Set the journals JBD2_FEATURE_INCOMPAT_64BIT on devices with more
than 32bit block sizes during mount time. This ensure proper record
lenth when writing to the journal.

This patch isn't in Ted's kernel.org directory and hasn't been in -mm.
Where did it come from? Is something amiss with ext4 patch management?

Please prepare patches using `diff -p'

It is not appropriate for the text "ext4" to appear in a JBD2 message.

Jose Santo posted it to linux-ext4 mailing list.

I agree this bug fix should included in Ted's git tree or mm tree. There
are other ext4 cleanups in this series that should goes to mm tree also.

This is part of ext4 code. Ext4 will set the 64-bit JBD2 flag if the fs
is larger than 32 bit blocks.
