New Revision: 331950
URL: https://svnweb.freebsd.org/changeset/base/331950
Log:
9434 Speculative prefetch is blocked by device removal code.
Device removal code does not set spa_indirect_vdevs_loaded for pools
that never experienced device removal. At least one visual consequence
of it is completely blocked speculative prefetcher. This patch sets
the variable in such situations.
