[PATCH 0/4] xfs: xfs_spaceman utility rework

[PATCH 0/4] xfs: xfs_spaceman utility rework

[Dhruvesh Rathore]

The original kernel patch that Dave wrote for xfs_spaceman implemented
FS_IOC_FIEMAPFS ioctl, here is the original fiemap extension patch:

http://oss.sgi.com/archives/xfs/2012-10/msg00363.html

These patches were not posted and were just forward ported to a current 
3.18-rc7+ for-next XFS tree and were pushed to the fiemapfs branch in Dave's
kernel tree at:

git://git.kernel.org/pub/scm/linux/kernel/git/dgc/linux-xfs.git


The original xfs_spaceman tool that Dave wrote to call the fiemap
interface and make use of it is here:

http://oss.sgi.com/archives/xfs/2012-10/msg00366.html

Dave just updated it to the 3.2.2 code base and pushed it to the
spaceman branch in this tree:

git://git.kernel.org/pub/scm/fs/xfs/xfsprogs-dev.git

The description of patches in this series are as follows:

1) [PATCH 1/4] xfs: Accounting for AGFL blocks in xfs_spaceman
	This patch adds functionality in xfs_spaceman allowing it to
	account for AG Free List blocks. 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.

These tree branches have just been updated (via rebase) with all the
changes in these patches integrated. Please update your trees and
review and test the updated patches. The patches have been
reshuffled and reworked, so please make sure you are happy with the
attributions in the commit messages for the new patches.

Cheers,

Dave.
