Fix a leak of abd_t that manifested mostly when using raidzN with at least as many columns as N (e.g. a four-disk raidz2 but not a three-disk raidz2). Sufficiently heavy raidz use would eventually run a system out of memory. Additionally: * Switch abd_cache arena to FIRSTFIT, which empirically improves perofrmance. * Make abd_chunk_cache more performant and debuggable. * Allocate the abd_zero_buf from abd_chunk_cache rather than the heap. * Don't try to reap non-existent qcaches in abd_cache arena. * KM_PUSHPAGE->KM_SLEEP when allocating chunks from their own arena Reviewed-by: Matthew Ahrens <mahrens@delphix.com> Reviewed-by: Alexander Motin <mav@FreeBSD.org> Signed-off-by: Jorgen Lundman <lundman@lundman.net> Co-authored-by: Sean Doran <smd@use.net> Closes #12295 |
