Jan Kara 30fac0f75d ext4: Do not reserve clusters when fs doesn't support extents ... When the filesystem doesn't support extents (like in ext2/3 compatibility modes), there is no need to reserve any clusters. Space estimates for writing are exact, hole punching doesn't need new metadata, and there are no unwritten extents to convert. This fixes a problem when filesystem still having some free space when accessed with a native ext2/3 driver suddently reports ENOSPC when accessed with ext4 driver.
