From 99b13c7f0bd35dd3cf2cacb61beb4557dc2b6f9b Mon Sep 17 00:00:00 2001 From: Dave Chinner Date: Thu, 7 Jul 2022 19:07:24 +1000 Subject: xfs: pass perag to xfs_ialloc_read_agi() xfs_ialloc_read_agi() initialises the perag if it hasn't been done yet, so it makes sense to pass it the perag rather than pull a reference from the buffer. This allows callers to be per-ag centric rather than passing mount/agno pairs everywhere. Signed-off-by: Dave Chinner Reviewed-by: Christoph Hellwig Reviewed-by: Darrick J.
