From 2e06df552a7cba13eb0046b9116a9aa26001ee2c Mon Sep 17 00:00:00 2001 From: Catherine Hoang Date: Tue, 10 May 2022 13:27:59 -0700 Subject: [PATCH] xfs: remove warning counters from struct xfs_dquot_res Warning counts are not used anywhere in the kernel. In addition, there are no use cases, test coverage, or documentation for this functionality. Remove the 'warnings' field from struct xfs_dquot_res and any other related code.
