+++ This bug was initially created as a clone of Bug #209840 +++ RHEL 4.5 clone The snapshot chunk size cannot be changed after snapshot creation so it is wrong to require userspace to supply the correct value in subsequent operations. This patch accepts 0 for the chunk_size parameter when the kernel already knows it. If it doesn't (at creation time) it still allows 0 and uses a default value (16KB).
