2011-07-13xfs: reshuffle dir2 headersChristoph Hellwig1-281/+0
Replace the current mess of dir2 headers with just three that have a clear purpose: - xfs_dir2_format.h for all format definitions, including the inline helpers to access our variable size structures - xfs_dir2_priv.h for all prototypes that are internal to the dir2 code and not needed by anything outside of the directory code. For this purpose xfs_da_btree.c, and phase6.c in xfs_repair are considered part of the directory code. - xfs_dir2.h for the public interface to the directory code In addition to the reshuffle I have also update the comments to not only match the new file structure, but also to describe the directory format better.

2011-07-08xfs: cleanup struct xfs_dir2_leafChristoph Hellwig1-6/+31
Simplify the confusing xfs_dir2_leaf structure. It is supposed to describe an XFS dir2 leaf format btree block, but due to the variable sized nature of almost all elements in it it can't actuall do anything close to that job. Remove the members that are after the first variable sized array, given that they could only be used for sizeof expressions that can as well just use the underlying types directly, and make the ents array a real C99 variable sized array. Also factor out the xfs_dir2_leaf_size, to make the sizing of a leaf entry which already was convoluted somewhat readable after using the longer type names in the sizeof expressions.

2011-07-08xfs: factor out xfs_dir2_leaf_find_entryChristoph Hellwig1-0/+3
Add a new xfs_dir2_leaf_find_entry helper to factor out some duplicate code from xfs_dir2_leaf_addname xfs_dir2_leafn_add. Found by Eric Sandeen using an automated code duplication checker.

2007-10-15[XFS] use filldir internallyChristoph Hellwig1-3/+3
Currently xfs has a rather complicated internal scheme to allow for different directory formats in IRIX. This patch rips all code related to this out and pushes useage of the Linux filldir callback into the lowlevel directory code. This does not make the code any less portable because filldir can be used to create dirents of all possible variations (including the IRIX ones as proved by the IRIX binary emulation code under arch/mips/). This patch get rid of an unessecary copy in the readdir path, about 400 lines of code and one of the last two users of the uio structure. This version is updated to deal with dmapi aswell which greatly simplifies the get_dirattrs code. The dmapi part has been tested using the get_dirattrs tools from the xfstest dmapi suite1 with various small and large directories.

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!
