Author: delphij Date: Sat Sep 13 16:26:14 2014 New Revision: 271526 URL: http://svnweb.freebsd.org/changeset/base/271526 Log: MFV r271510: Enforce 4K as smallest indirect block size (previously the smallest indirect block size was 1K but that was never used). This makes some space estimates more accurate and uses less memory for some data structures. Illumos issue: 5141 zfs minimum indirect block size is 4K MFC after: 2 weeks Modified: head/sys/cddl/boot/zfs/zfsimpl.h head/sys/cddl/contrib/opensolaris/uts/common/fs/zfs/sys/dnode.h Directory Properties: head/sys/cddl/contrib/opensolaris/ (props changed) Modified: head/sys/cddl/boot/zfs/zfsimpl.h ============================================================================== --- head/sys/cddl/boot/zfs/zfsimpl.h Sat Sep 13 16:07:43 2014 (r271525) +++ head/sys/cddl/boot/zfs/zfsimpl.h Sat Sep 13 16:26:14 2014 (r271526) @@ -840,7 +840,7 @@ struct uberblock { * Fixed constants. */ #define DNODE_SHIFT 9 /* 512 bytes */ -#define DN_MIN_INDBLKSHIFT 10 /* 1k */ +#define DN_MIN_INDBLKSHIFT 12 /* 4k */ #define DN_MAX_INDBLKSHIFT 14 /* 16k */ #define DNODE_BLOCK_SHIFT 14 /* 16k */ #define DNODE_CORE_SIZE 64 /* 64 bytes for dnode sans blkptrs */ Modified: head/sys/cddl/contrib/opensolaris/uts/common/fs/zfs/sys/dnode.h ============================================================================== --- head/sys/cddl/contrib/opensolaris/uts/common/fs/zfs/sys/dnode.h Sat Sep 13 16:07:43 2014 (r271525) +++ head/sys/cddl/contrib/opensolaris/uts/common/fs/zfs/sys/dnode.h Sat Sep 13 16:26:14 2014 (r271526) @@ -56,7 +56,7 @@ extern "C" { * Fixed constants. */ #define DNODE_SHIFT 9 /* 512 bytes */ -#define DN_MIN_INDBLKSHIFT 10 /* 1k */ +#define DN_MIN_INDBLKSHIFT 12 /* 4k */ #define DN_MAX_INDBLKSHIFT 14 /* 16k */ #define DNODE_BLOCK_SHIFT 14 /* 16k */ #define DNODE_CORE_SIZE 64 /* 64 bytes for dnode sans blkptrs */
