From 9e253954acf53227f33d307f5ac5ff94c1ca5880 Mon Sep 17 00:00:00 2001 From: "Darrick J. Wong" Date: Tue, 12 Oct 2021 15:29:33 -0700 Subject: [PATCH] xfs: compact deferred intent item structures Rearrange these structs to reduce the amount of unused padding bytes. This saves eight bytes for each of the three structs changed here, which means they're now all (rmap/bmap are 64 bytes, refc is 32 bytes) even powers of two. Signed-off-by: Darrick J.
