write support for preallocated blocks This patch adds write support to the uninitialized extents that get created when a preallocation is done using fallocate(). It takes care of splitting the extents into multiple (upto three) extents and merging the new split extents with neighbouring ones, if possible. Signed-off-by: Amit Arora <aarora@in.ibm.com>
