* completion arc_read_done() allocates ARC buffer(s) as needed, potentially
* sharing one of them with the physical ABD buffer.
*
* In case of write arc_alloc_buf() allocates ARC buffer to be filled with
* data. Then after compression and/or encryption arc_write_ready() allocates
* and fills (or potentially shares) physical (b_pabd) or raw (b_rabd) ABD
* buffer. On disk write completion arc_write_done() assigns the header its
* new identity (b_dva + b_birth) and inserts into ARC hash.
*
* In case of partial overwrite the old data is read first as described. Then
* arc_release() either allocates new anonymous ARC header and moves the ARC
* buffer to it, or reuses the old ARC header by discarding its identity and
* removing it from ARC hash. After buffer modification normal write process
* follows as described.
