xfs: use actual inode count for sparse records in bulkstat/inumbers

2015-05-28T23:04:19+00:00

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

xfs: pass mp to XFS_WANT_CORRUPTED_RETURN

2015-02-23T11:39:13+00:00

Today, if we hit an XFS_WANT_CORRUPTED_RETURN we don't print any information about which filesystem hit it. Passing in the mp allows us to print the filesystem (device) name, which is a pretty critical piece of information. Tested by running fsfuzzer 'til I hit some.

xfs: fix set-but-unused warnings

2014-12-03T22:43:17+00:00

The kernel compile doesn't turn on these checks by default, so it's only when I do a kernel-user sync that I find that there are lots of compiler warnings waiting to be fixed. Fix up these set-but-unused warnings. Signed-off-by: Dave Chinner Reviewed-by: Eric Sandeen Reviewed-by: Christoph Hellwig Signed-off-by: Dave Chinner

xfs: track bulkstat progress by agino

2014-11-06T21:33:52+00:00

The bulkstat main loop progress is tracked by the "lastino" variable, which is a full 64 bit inode. However, the loop actually works on agno/agino pairs, and so there's a significant disconnect between the rest of the loop and the main cursor. Convert this to use the agino, and pass the agino into the chunk formatting function and convert it too. This gets rid of the inconsistency in the loop processing, and finally makes it simple for us to skip inodes at any point in the loop simply by incrementing the agino cursor. cc: # 3.17 Signed-off-by: Dave Chinner Reviewed-by: Brian Foster Signed-off-by: Dave Chinner
