2014-06-25T04:57:36+00:00

Move all the header files that are shared with userspace into libxfs. This is done as one big chunk simpy to get it done quickly. Signed-off-by: Dave Chinner Reviewed-by: Brian Foster Signed-off-by: Dave Chinner

xfs: remove mp->m_dir_geo from directory logging

2014-06-06T05:20:54+00:00

We don't pass the xfs_da_args or the geometry all the way down to the directory buffer logging code, hence we have to use mp->m_dir_geo here. Fix this to use the geometry passed via the xfs_da_args, and convert all the directory logging functions for consistency.

xfs: reduce direct usage of mp->m_dir_geo

2014-06-06T05:20:32+00:00

There are many places in the directory code were we don't pass the args into and so have to extract the geometry direct from the mount structure. Push the args or the geometry into these leaf functions so that we don't need to grab it from the struct xfs_mount. This, in turn, brings use to the point where directory geometry is no longer a property of the struct xfs_mount; it is not a global property anymore, and hence we can start to consider per-directory configuration of physical geometries. Start by converting the xfs_dir_isblock/leaf code - pass in the xfs_da_args and convert the readdir code to use xfs_da_args like the rest of the directory code to pass information around.

xfs: introduce directory geometry structure

2014-06-06T05:01:58+00:00

The directory code has a dependency on the struct xfs_mount to supply the directory block geometry. Block size, block log size, and other parameters are pre-caclulated in the struct xfs_mount or access directly from the superblock embedded in the struct xfs_mount. Extract all of this geometry information out of the struct xfs_mount and superblock and place it into a new struct xfs_da_geometry defined by the directory code. Allocate and initialise it at mount time, and attach it to the struct xfs_mount so it canbe passed back into the directory code appropriately rather than using the struct xfs_mount.

xfs: convert directory vector functions to constants

xfs: convert directory vector functions to constants

xfs: vectorise encoding/decoding directory headers

2013-10-30T18:47:22+00:00

Conversion from on-disk structures to in-core header structures currently relies on magic number checks. If the magic number is wrong, but one of the supported values, we do the wrong thing with the encode/decode operation. Split these functions so that there are discrete operations for the specific directory format we are handling. In doing this, move all the header encode/decode functions to xfs_da_format.c as they are directly manipulating the on-disk format. It should be noted that all the growth in binary size is from xfs_da_format.c - the rest of the code actaully shrinks. text data bss dec hex filename 794490 96802 1096 892388 d9de4 fs/xfs/xfs.o.orig 792986 96802 1096 890884 d9804 fs/xfs/xfs.o.p1 792350 96802 1096 890248 d9588 fs/xfs/xfs.o.p2 789293 96802 1096 887191 d8997 fs/xfs/xfs.o.p3 789005 96802 1096 886903 d8997 fs/xfs/xfs.o.p4 789061 96802 1096 886959 d88af fs/xfs/xfs.o.p5 789733 96802 1096 887631 d8b4f fs/xfs/xfs.o.p6 791421 96802 1096 889319 d91e7 fs/xfs/xfs.o.p7 Signed-off-by: Dave Chinner Reviewed-by: Ben Myers Signed-off-by: Ben Myers

xfs: vectorise DA btree operations

2013-10-30T18:43:28+00:00

The remaining non-vectorised code for the directory structure is the node format blocks. This is shared with the attribute tree, and so is slightly more complex to vectorise. Introduce a "non-directory" directory ops structure that is attached to all non-directory inodes so that attribute operations can be vectorised for all inodes. Once we do this, we can vectorise all the da btree operations. Because this patch adds more infrastructure than it removes the binary size does not decrease: text data bss dec hex filename 794490 96802 1096 892388 d9de4 fs/xfs/xfs.o.orig 792986 96802 1096 890884 d9804 fs/xfs/xfs.o.p1 792350 96802 1096 890248 d9588 fs/xfs/xfs.o.p2 789293 96802 1096 887191 d8997 fs/xfs/xfs.o.p3 789005 96802 1096 886903 d8997 fs/xfs/xfs.o.p4 789061 96802 1096 886959 d88af fs/xfs/xfs.o.p5 789733 96802 1096 887631 d8b4f fs/xfs/xfs.o.p6 Signed-off-by: Dave Chinner Reviewed-by: Ben Myers Signed-off-by: Ben Myers
