[XFS] 929045 567344 This mod re-organizes some of the in-core file extent
code to prepare for an upcoming mod which will introduce multi-level in-core extent allocations. Although the in-core extent management is using a new code path in this mod, the functionality remains the same. Major changes include: - Introduce 10 new subroutines which re-orgainze the existing code but do NOT change functionality: xfs_iext_get_ext() xfs_iext_insert() xfs_iext_add() xfs_iext_remove() xfs_iext_remove_inline() xfs_iext_remove_direct() xfs_iext_realloc_direct() xfs_iext_direct_to_inline() xfs_iext_inline_to_direct() xfs_iext_destroy() - Remove 2 subroutines (functionality moved to new subroutines above): xfs_iext_realloc() -replaced by xfs_iext_add() and xfs_iext_remove() xfs_bmap_insert_exlist() - replaced by xfs_iext_insert() xfs_bmap_delete_exlist() - replaced by xfs_iext_remove() - Replace all hard-coded (indexed) extent assignments with a call to xfs_iext_get_ext() - Replace all extent record pointer arithmetic (ep++, ep--, base + lastx,..) with calls to xfs_iext_get_ext() - Update comments to remove the idea of a single "extent list" and introduce "extent record" terminology instead SGI-PV: 928864 SGI-Modid: xfs-linux-melb:xfs-kern:207390a Signed-off-by: Mandy Kirkconnell <alkirkco@sgi.com> Signed-off-by: Nathan Scott <nathans@sgi.com>
