Illumos 5408 - managing ZFS cache devices requires lots of RAM
5408 managing ZFS cache devices requires lots of RAM Reviewed by: Christopher Siden <[email protected]> Reviewed by: George Wilson <[email protected]> Reviewed by: Matthew Ahrens <[email protected]> Reviewed by: Don Brady <[email protected]> Reviewed by: Josef 'Jeff' Sipek <[email protected]> Approved by: Garrett D'Amore <[email protected]> Porting notes: Due to the restructuring of the ARC-related structures, this patch conflicts with at least the following existing ZoL commits: 6e1d7276c94cbd7c2e19f9232f6ba4bafa62dbe0 Fix inaccurate arcstat_l2_hdr_size calculations The ARC_SPACE_HDRS constant no longer exists and has been somewhat equivalently replaced by HDR_L2ONLY_SIZE. e0b0ca983d6897bcddf05af2c0e5d01ff66f90db Add visibility in to cached dbufs The new layering of l{1,2}arc_buf_hdr_t within the arc_buf_hdr struct requires additional structure member names to be used when referencing the inner items. Also, the presence of L1 or L2 inner member is indicated by flags using the new HDR_HAS_L{1,2}HDR macros. Ported by: Tim Chase <[email protected]> Signed-off-by: Brian Behlendorf <[email protected]>
