  ext4: fix type-widening bug in inode table readahead code (2013-04-23 08:59:35 -0400)

----------------------------------------------------------------
Mostly performance and bug fixes, plus some cleanups.  The one new
feature this merge window is a new ioctl EXT4_IOC_SWAP_BOOT which
allows installation of a hidden inode designed for boot loaders.
