From 41176a68e3f710630feace536d0277a092e206b5 Mon Sep 17 00:00:00 2001 From: Brian Foster Date: Tue, 6 Nov 2012 09:50:42 -0500 Subject: xfs: create function to scan and clear EOFBLOCKS inodes xfs_inodes_free_eofblocks() implements scanning functionality for EOFBLOCKS inodes. It uses the AG iterator to walk the tagged inodes and free post-EOF blocks via the xfs_inode_free_eofblocks() execute function. The scan can be invoked in best-effort mode or wait (force) mode. A best-effort scan (default) handles all inodes that do not have a dirty cache and we successfully acquire the io lock via trylock. In wait mode, we continue to cycle through an AG until all inodes are handled.
