Create all new directories with OCFS2_INLINE_DATA_FL and the inline data bytes formatted as an empty directory. Inode size field reflects the actual amount of inline data available, which makes searching for dirent space very similar to the regular directory search. Inline-data directories are automatically pushed out to extents on any insert request which is too large for the available space.

This splits out extent based directory read support and implements inline-data versions of those functions. All knowledge of inline-data versus extent based directories is internalized. For lookups the code uses ocfs2_find_entry_id(), full dir iterations make use of ocfs2_dir_foreach_blk_id().

This fixes up write, truncate, mmap, and RESVSP/UNRESVP to understand inline inode data. For the most part, the changes to the core write code can be relied on to do the heavy lifting. Any code calling ocfs2_write_begin (including shared writeable mmap) can count on it doing the right thing with respect to growing inline data to an extent tree. Size reducing truncates, including UNRESVP can simply zero that portion of the inode block being removed. Size increasing truncatesm, including RESVP have to be a little bit smarter and grow the inode to an extent tree if necessary.

This hooks up ocfs2_readpage() to populate a page with data from an inode block. Direct IO reads from inline data are modified to fall back to buffered I/O. Appropriate checks are also placed in the extent map code to avoid reading an extent list when inline data might be stored.

Add the disk, network and memory structures needed to support data in inode. Struct ocfs2_inline_data is defined and embedded in ocfs2_dinode for storing inline data. A new inode field, i_dyn_features, is added to facilitate tracking of dynamic inode state. Since it will be used often, we want to mirror it on ocfs2_inode_info, and transfer it via the meta data lvb.

ocfs2_rename() does direct manipulation of the dirent it's gotten back from a directory search. Wrap this manipulation inside of a function so that we can transparently change directory update behavior in the future. As an added bonus, this gets rid of an ugly macro.

A couple paths which needed to just match a parent dir + name pair to an inode number were a bit messy because they had to deal with ocfs2_find_files_on_disk() which returns a larger number of values. Provide a convenience function, ocfs2_lookup_ino_from_name() which internalizes all the extra accounting.

We can preserve the behavior of ocfs2_empty_dir(), while getting rid of the open coded directory walk by just providing a smart filldir callback. This also automatically gets to use the dir readahead code, though in this case any advantage is minor at best.

filldir_t can take this, so don't turn de->inode into a 32 bit value. Right now this doesn't make a difference since no ocfs2 inodes overflow that, but it could be a nasty surprise later on if some kernel code is calling ocfs2_dir_foreach_blk() and expecting real inode numbers back...

The code for adding, removing, deleting directory entries was splattered all over namei.c. I'd rather have this all centralized, so that it's easier to make changes for inline dir data, and eventually indexed directories. None of the code in any of the functions was changed. I only removed the static keyword from some prototypes so that they could be exported. Signed-off-by: NMark Fasheh <mark.fasheh@oracle.com> Reviewed-by: NJoel Becker <joel.becker@oracle.com>

We'll want to reuse most of this when pushing inline data back out to an extent. Keeping this part as a seperate patch helps to keep the upcoming changes for write support uncluttered. The core portion of ocfs2_zero_cluster_pages() responsible for making sure a page is mapped and properly dirtied is abstracted out into it's own function, ocfs2_map_and_dirty_page(). Actual functionality doesn't change, though zeroing becomes optional. We also turn part of ocfs2_free_write_ctxt() into a common function for unlocking and freeing a page array. This operation is very common (and uniform) for Ocfs2 cluster sizes greater than page size, so it makes sense to keep the code in one place.

By doing this, we can remove any higher level logic which has to have knowledge of btree functionality - any callers of ocfs2_write_begin() can now expect it to do anything necessary to prepare the inode for new data.

Currently find_legacy_serial_ports() can find no serial ports on the OPB with flattened device tree. Thus no legacy boot console can be initialized. Just the early udbg console works, which is initialized with udbg_init_44x_as1 on the UART's physical address specified in kernel config. This happens because we look for ns16750 serial devices only and expect opb node to have a device type property. This patch makes it look for ns16550-compatible devices and use of_device_is_compatible() for opb in case device type is not specified.

This makes the kernel use 1TB segments for all kernel mappings and for user addresses of 1TB and above, on machines which support them (currently POWER5+, POWER6 and PA6T). We detect that the machine supports 1TB segments by looking at the ibm,processor-segment-sizes property in the device tree. We don't currently use 1TB segments for user addresses < 1T, since that would effectively prevent 32-bit processes from using huge pages unless we also had a way to revert to using 256MB segments. That would be possible but would involve extra complications (such as keeping track of which segment size was used when HPTEs were inserted) and is not addressed here. Parts of this patch were originally written by Ben Herrenschmidt. Signed-off-by: NPaul Mackerras <paulus@samba.org>
