+commit 43a498e938887956f393b5e45ea6ac79cc5f4b84
+Author: Theodore Ts'o <tytso@mit.edu>

+Subject: resize2fs: use Direct I/O when reading the superblock for
+ online resizes
+ 
+ If the file system is mounted, the superblock can be changing while
+ resize2fs is trying to read the superblock, resulting in checksum
+ failures.  One way of avoiding this problem is read the superblock
+ using Direct I/O, since the kernel makes sure that what gets written
+ to disk is self-consistent.
