The previous version of xfs_spaceman failed to account for AGFL blocks as they aren't found by walking the free space btrees, so we have to walk each AGFL to find them. A new function xfs_alloc_agfl_freespace_map() is added which will walk the free extents in AGFL and account for these AGFL blocks by using agf_flfirst, agf_fllast and agf_flcount fields. 2) [PATCH 2/4] xfsprogs: Addition in debug option -d of xfs_spaceman This patch allows adding a title for the contents which are printed when xfs_spaceman is run with -d debug option from command line. The titles added are agno, agbno and len. 3) [PATCH 3/4] xfs: Adding XFS_IOC_FIEMAPFS ioctl for use in xfs_spaceman This patch is concerned with the changes made in kernel space code for adding a new XFS specific ioctl XFS_IOC_FIEMAPFS in xfs_spaceman. This ioctl will replace a file based ioctl FS_IOC_FIEMAPFS, and allow us to modify the ioctl as per requirement in the future. 4) [PATCH 4/4] xfprogs: Adding XFS_IOC_FIEMAPFS ioctl for use in xfs_spaceman This patch is concerened with the changes made in user space code for using XFS_IOC_FIEMAPFS ioctl in xfs_spaceman, which will replace FS_IOC_FIEMAPFS and make use of fiemap plumbing. Comments, thoughts etc are welcome. Regards, A-DRS. _______________________________________________ xfs mailing list xfs@oss.sgi.com http://oss.sgi.com/mailman/listinfo/xfs
