From 12d0714d4bdd591d9cd3bce692c831da2c2a0cfc Mon Sep 17 00:00:00 2001 From: Brian Foster Date: Fri, 29 May 2015 09:04:19 +1000 Subject: [PATCH] xfs: use actual inode count for sparse records in bulkstat/inumbers The bulkstat and inumbers mechanisms make the assumption that inode records consist of a full 64 inode chunk in several places. For example, this is used to track how many inodes have been processed overall as well as to determine whether a record has allocated inodes that must be handled. This assumption is invalid for sparse inode records. While sparse inodes will be marked as free in the ir_free mask, they are not accounted as free in ir_freecount because they cannot be allocated. Therefore, ir_freecount may be less than 64 inodes in an inode record for which all physically allocated inodes are free (and in turn ir_freecount < 64 does not signify that the record has allocated inodes). The new in-core inobt record format includes the ir_count field. This holds the number of true, physical inodes tracked by the record. The in-core ir_count field is always valid as it is hardcoded to XFS_INODES_PER_CHUNK when sparse inodes is not enabled. Use ir_count to handle inode records correctly in bulkstat in a generic manner. Signed-off-by: Brian Foster Reviewed-by: Dave Chinner Signed-off-by: Dave Chinner --- Reading git-format-patch failed
