[PATCH] block: fallocate: avoid false positive on collision detection

Align start and end on page boundaries before calling invalidate_inode_pages2_range. This might allow us to miss a collision if the write and the discard were done to the same page and do overlap but it is still better than returning -EBUSY if those writes didn't overlap. Signed-off-by: Maxim
