fallocate support in ext4
This patch implements ->fallocate() inode operation in ext4. With this patch users of ext4 file systems will be able to use fallocate() system call for persistent preallocation. Current implementation only supports preallocation for regular files (directories not supported as of date) with extent maps. This patch does not support block-mapped files currently. Only FALLOC_ALLOCATE and FALLOC_RESV_SPACE modes are being supported as of now. Signed-off-by: Amit Arora <aarora@in.ibm.com>
