5408 managing ZFS cache devices requires lots of RAM Reviewed by: Christopher Siden <christopher.siden@delphix.com> Reviewed by: George Wilson <george.wilson@delphix.com> Reviewed by: Matthew Ahrens <mahrens@delphix.com> Reviewed by: Don Brady <dev.fs.zfs@gmail.com> Reviewed by: Josef 'Jeff' Sipek <josef.sipek@nexenta.com> Approved by: Garrett D'Amore <garrett@damore.org> Porting notes: Due to the restructuring of the ARC-related structures, this patch conflicts with at least the following existing ZoL commits:6e1d7276c9Fix inaccurate arcstat_l2_hdr_size calculations The ARC_SPACE_HDRS constant no longer exists and has been somewhat equivalently replaced by HDR_L2ONLY_SIZE.e0b0ca983dAdd 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 <tim@chase2k.com> Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov>
