From c3c4ecb529c5a1f0590cffb70649d407ee79b8a8 Mon Sep 17 00:00:00 2001 From: Chandan Babu R Date: Wed, 9 Mar 2022 12:58:37 +0000 Subject: xfs: Enable bulkstat ioctl to support 64-bit per-inode extent counters The following changes are made to enable userspace to obtain 64-bit extent counters, 1. Carve out a new 64-bit field xfs_bulkstat->bs_extents64 from xfs_bulkstat->bs_pad[] to hold 64-bit extent counter. 2. Define the new flag XFS_BULK_IREQ_BULKSTAT for userspace to indicate that it is capable of receiving 64-bit extent counters. Reviewed-by: Dave Chinner Reviewed-by: Darrick J.
