Hi Mingming,

Here are the new patches which use new fallocate inode interface. I have
made following changes to the previous patchset:

1. Removed ioctl portion of the code from the preallocation patch.
2. Added ext4_fallocate() to support the new fallocate inode operation,
which will be called from the sys_fallocate() system call code.
3. Fixed the endian error which you observed in the "write support for
uninitialized extents" patch.
