If anyone has any objections, please let me know. ------------------ From: "Darrick J. Wong" [ Upstream commit f29c3e745dc253bf9d9d06ddc36af1a534ba1dd0 ] [ 6.1: excluded changes to trace.h as xchk_rtsum_record_free does not exist yet ] XFS uses xfs_rtblock_t for many different uses, which makes it much more difficult to perform a unit analysis on the codebase. One of these (ab)uses is when we need to store the length of a free space extent as stored in the realtime bitmap. Because there can be up to 2^64 realtime extents in a filesystem, we need a new type that is larger than xfs_rtxlen_t for callers that are querying the bitmap directly. This means scrub and growfs. Create this type as "xfs_rtbxlen_t" and use it to store 64-bit rtx lengths. 'b' stands for 'bitmap' or 'big'; reader's choice. Signed-off-by: Darrick J.
