7086 ztest attempts dva_get_dsize_sync on an embedded blockpointer
illumos/illumos-gate@926549256bhttps://github.com/illumos/illumos-gate/commit/926549256b71acd595f69b236779ff6b7

In dbuf_dirty(), we need to grab the dn_struct_rwlock before looking at the
db_blkptr, to prevent it from being changed by syncing context.
Otherwise we may see that ztest got a segfault from this stack:

Looking into it a bit, we see that this is an embedded blockpointer, so
BP_GET_NDVAS should have returned 0:
b32b240::blkptr

Instead, it looks like another thread is modifying this blockpointer:

When reading compressed data from disk, the ARC should keep the compressed
block cached and only decompress it when consumers access the block. The
uncompressed data should be short-lived allowing the ARC to cache a much larger
amount of data. The DMU would also maintain a smaller cache of uncompressed
blocks to minimize the impact of decompressing frequently accessed blocks.

Althought cryptotest itself has a -z mode to test all algorithms at a variety
of sizes, this script allows us to be more selective. Threads and buffer sizes
move in powers of two from 1, for threads, and 256 for buffer sizes.
e.g. cryptorun.sh aes 4 512
Test aes with 1, 2 and 4 processes, and at sizes of 256 and 512 bytes.
