Re: [PATCH v4 0/3] v2v: Add -o rhv-upload output mode.
...o
guarantees
that the data will be available after a crash. There is no user
interface to know if a write is purely an overwrite. On file
systems
using copy-on-write semantics (e.g., btrfs) an overwrite of existing
allocated blocks is impossible. When writing into preal‐ located
space, many file systems also require calls into the block
allocator,
which this system call does not sync out to disk. This system call
does not flush disk write caches and thus does not provide any data
integrity on systems with volatile disk write caches...
