2008-10-30[XFS] make btree root in inode support genericChristoph Hellwig1-20/+27
The bmap btree is rooted in the inode and not in a disk block. Make the support for this feature more generic by adding a btree flag to for this feature instead of relying on the XFS_BTNUM_BMAP btnum check. Also clean up xfs_btree_get_block where this new flag is used. Based upon a patch from Dave Chinner.

2008-10-30[XFS] split up xfs_btree_init_cursorChristoph Hellwig1-103/+4
xfs_btree_init_cursor contains close to little shared code for the different btrees and will get even more non-common code in the future. Split it up into one routine per btree type. Because xfs_btree_dup_cursor needs to call the init routine for a generic btree cursor add a new btree operation vector that contains a dup_cursor method that initializes a new cursor based on an existing one. The btree operations vector is based on an idea and code from Dave Chinner and will grow more entries later during this series.

2008-10-30[XFS] kill struct xfs_btree_hdrChristoph Hellwig1-6/+6
This type is only embedded in struct xfs_btree_block and never used directly. By moving the fields directly into struct xfs_btree_block a lot of the macros for struct xfs_btree_sblock and struct xfs_btree_lblock can be used for struct xfs_btree_block too now which helps greatly with some of the migrations during implementing the generic btree code.

2008-08-13[XFS] Use the same btree_cur union member for alloc and inobt trees.Christoph Hellwig1-9/+9
The alloc and inobt btree use the same agbp/agno pair in the btree_cur union. Make them use the same bc_private.a union member so that code for these two short form btree implementations can be shared.

2008-08-13[XFS] small cleanups in xfs_btree.cChristoph Hellwig1-57/+30
Remove unneeded xfs_btree_get_block forward declaration. Move xfs_btree_firstrec next to xfs_btree_lastrec.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
