* xfs: remove m_attroffsetChristoph Hellwig2009-03-291-0/+4
| | | | | | | | | | | | | With the upcoming v3 inodes the default attroffset needs to be calculated for each specific inode, so we can't cache it in the superblock anymore. Also replace the assert for wrong inode sizes with a proper error check also included in non-debug builds. Note that the ENOSYS return for that might seem odd, but that error is returned by xfs_mount_validate_sb for all theoretically valid but not supported filesystem geometries.

* [XFS] convert xfs_getbmap to take formatter functionsEric Sandeen2008-12-011-4/+7
| | | | | | | | | | | | | | | | | | | | Preliminary work to hook up fiemap, this allows us to pass in an arbitrary formatter to copy extent data back to userspace. The formatter takes info for 1 extent, a pointer to the user "thing*" and a pointer to a "filled" variable to indicate whether a userspace buffer did get filled in (for fiemap, hole "extents" are skipped). I'm just using the getbmapx struct as a "common denominator" because as far as I can see, it holds all info that any formatters will care about. ("*thing" because fiemap doesn't pass the user pointer around, but rather has a pointer to a fiemap info structure, and helpers associated with it) Signed-off-by: Eric Sandeen <sandeen@sandeen.net> Reviewed-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Niv Sardi <xaiki@sgi.com>

* [XFS] Restore the lowspace extent allocator algorithmLachlan McIlroy2008-07-281-1/+12
| | | | | | | | | | | | | | | | | When free space is running low the extent allocator may choose to allocate an extent from an AG without leaving sufficient space for a btree split when inserting the new extent (see where xfs_bmap_btalloc() sets minleft to 0). In this case the allocator will enable the lowspace algorithm which is supposed to allow further allocations (such as btree splits and newroots) to allocate from sequential AGs. This algorithm has been broken for a long time and this patch restores its behaviour.

* [XFS] decontaminate vnode operations from behavior detailsChristoph Hellwig2007-10-151-1/+1
| | | | | | | | | | | | | | | All vnode ops now take struct xfs_inode pointers and the behaviour related glue is split out into methods of it's own. This required fixing xfs_create/mkdir/symlink to not mess with the inode pointer but rather use a separate boolean for error handling. Thanks to Dave Chinner for that fix.

* [XFS] 929045 567344 This mod introduces multi-level in-core file extentMandy Kirkconnell2006-03-141-0/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | functionality, building upon the new layout introduced in mod xfs-linux:xfs-kern:207390a. The new multi-level extent allocations are only required for heavily fragmented files, so the old-style linear extent list is used on files until the extents reach a pre-determined size of 4k. 4k buffers are used because this is the system page size on Linux i386 and systems with larger page sizes don't seem to gain much, if anything, by using their native page size as the extent buffer size. Also, using 4k extent buffers everywhere provides a consistent interface for CXFS across different platforms. The 4k extent buffers are managed by an indirection array (xfs_ext_irec_t) which is basically just a pointer array with a bit of extra information to keep track of the number of extents in each buffer as well as the extent offset of each buffer. Major changes include: - Add multi-level in-core file extent functionality to the xfs_iext_ subroutines introduced in mod: xfs-linux:xfs-kern:207390a - Introduce 13 new subroutines which add functionality for multi-level in-core file extents: xfs_iext_add_indirect_multi() xfs_iext_remove_indirect() xfs_iext_realloc_indirect() xfs_iext_indirect_to_direct() xfs_iext_bno_to_irec() xfs_iext_idx_to_irec() xfs_iext_irec_init() xfs_iext_irec_new() xfs_iext_irec_remove() xfs_iext_irec_compact() xfs_iext_irec_compact_pages() xfs_iext_irec_compact_full() xfs_iext_irec_update_extoffs() SGI-PV: 928864 SGI-Modid: xfs-linux-melb:xfs-kern:207393a Signed-off-by: Mandy Kirkconnell <alkirkco@sgi.com> Signed-off-by: Nathan Scott <nathans@sgi.com>

| | | | | | | | | | | | | | the data/attr forks now grow up/down from either end of the literal area, rather than dividing the literal area into two chunks and growing both upward.

It is self enabling, but can be forced on/off via the attr2/noattr2 mount options. SGI-PV: 941645 SGI-Modid: xfs-linux:xfs-kern:23835a Signed-off-by: Nathan Scott <nathans@sgi.com>

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!
