From 1b5560488d1ab7c932f6f99385b41116838c3486 Mon Sep 17 00:00:00 2001 From: Brian Foster Date: Tue, 6 Nov 2012 09:50:45 -0500 Subject: [PATCH] xfs: support multiple inode id filtering in eofblocks scan Enhance the eofblocks scan code to filter based on multiply specified inode id values. When multiple inode id values are specified, only inodes that match all id values are selected.
