2013-10-23xfs: decouple inode and bmap btree header filesDave Chinner
Currently the xfs_inode.h header has a dependency on the definition of the BMAP btree records as the inode fork includes an array of xfs_bmbt_rec_host_t objects in it's definition. Move all the btree format definitions from xfs_btree.h, xfs_bmap_btree.h, xfs_alloc_btree.h and xfs_ialloc_btree.h to xfs_format.h to continue the process of centralising the on-disk format definitions. With this done, the xfs inode definitions are no longer dependent on btree header files. The enables a massive culling of unnecessary includes, with close to 200 #include directives removed from the XFS kernel code base.

2013-10-23xfs: decouple log and transaction headersDave Chinner
xfs_trans.h has a dependency on xfs_log.h for a couple of structures. Most code that does transactions doesn't need to know anything about the log, but this dependency means that they have to include xfs_log.h. Decouple the xfs_trans.h and xfs_log.h header files and clean up the includes to be in dependency order. In doing this, remove the direct include of xfs_trans_reserve.h from xfs_trans.h so that we remove the dependency between xfs_trans.h and xfs_mount.h. Hence the xfs_trans.h include can be moved to the indicate the actual dependencies other header files have on it. Note that these are kernel only header files, so this does not translate to any userspace changes at all.

2013-08-12xfs: split out transaction reservation codeDave Chinner
The transaction reservation size calculations is used by both kernel and userspace, but most of the transaction code in xfs_trans.c is kernel specific. Split all the transaction reservation code out into it's own files to make sharing with userspace simpler. This just leaves kernel-only definitions in xfs_trans.h, so it doesn't need to be shared with userspace anymore, either.

2013-08-12xfs: separate dquot on disk format definitions out of xfs_quota.hDave Chinner
The on disk format definitions of the on-disk dquot, log formats and quota off log formats are all intertwined with other definitions for quotas. Separate them out into their own header file so they can easily be shared with userspace.

2013-06-28xfs: Remove incore use of XFS_OQUOTA_ENFD and XFS_OQUOTA_CHKDChandra Seetharaman
Remove all incore use of XFS_OQUOTA_ENFD and XFS_OQUOTA_CHKD. Instead, start using XFS_GQUOTA_.* XFS_PQUOTA_.* counterparts for GQUOTA and PQUOTA respectively. On-disk copy still uses XFS_OQUOTA_ENFD and XFS_OQUOTA_CHKD. Read and write of the superblock does the conversion from *OQUOTA* to *[PG]QUOTA*.

2012-09-18userns: Convert qutoactlEric W. Biederman
Update the quotactl user space interface to successfull compile with user namespaces support enabled and to hand off quota identifiers to lower layers of the kernel in struct kqid instead of type and qid pairs. The quota on function is not converted because while it takes a quota type and an id. The id is the on disk quota format to use, which is something completely different. The signature of two struct quotactl_ops methods were changed to take struct kqid argumetns get_dqblk and set_dqblk. The dquot, xfs, and ocfs2 implementations of get_dqblk and set_dqblk are minimally changed so that the code continues to work with the change in parameter type. This is the first in a series of changes to always store quota identifiers in the kernel in struct kqid and only use raw type and qid values when interacting with on disk structures or userspace. Always using struct kqid internally makes it hard to miss places that need conversion to or from the kernel internal values.

2012-05-14xfs: move xfsagino_t to xfs_types.hDave Chinner
Untangle the header file includes a bit by moving the definition of xfs_agino_t to xfs_types.h. This removes the dependency that xfs_ag.h has on xfs_inum.h, meaning we don't need to include xfs_inum.h everywhere we include xfs_ag.h.

2011-08-12xfs: remove subdirectoriesChristoph Hellwig
Use the move from Linux 2.6 to Linux 3.x as an excuse to kill the annoying subdirectories in the XFS source code. Besides the large amount of file rename the only changes are to the Makefile, a few files including headers with the subdirectory prefix, and the binary sysctl compat code that includes a header under fs/xfs/ from kernel/.
