Log: MFC r305332: MFV r304159: 7277 zdb should be able to print zfs_dbgmsg's illumos/illumos-gate@29bdd2f916366ece37c4748bca6b3d61f57a223b https://github.com/illumos/illumos-gate/commit/29bdd2f916366ece37c4748bca6b3d61f 57a223b https://www.illumos.org/issues/7277 ztest always prints the debug messages (zfs_dbgmsg()) by calling zfs_dbgmsg_print(). We should add a flag to zdb to make it do this as well before exiting.
