* ocfs2: Read support for inline dataMark Fasheh2007-10-122-4/+82
| | | | | | | | | | 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.

* ocfs2: Structure updates for inline dataMark Fasheh2007-10-126-4/+57
| | | | | | | | | | | | | | 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: Cleanup dirent size checkMark Fasheh2007-10-121-8/+28
| | | | | | | | | The check to see if a new dirent would fit in an old one is pretty ugly, and it's done at least twice. Clean things up by putting this in it's own easier-to-read function. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com> Reviewed-by: Joel Becker <joel.becker@oracle.com>
* ocfs2: Rename cleanupsMark Fasheh2007-10-123-31/+47
| | | | | | | | | | 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.

* ocfs2: Provide convenience function for ino lookupMark Fasheh2007-10-125-21/+25
| | | | | | | | | | | 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.

* ocfs2: Implement ocfs2_empty_dir() as a caller of ocfs2_dir_foreach()Mark Fasheh2007-10-122-52/+46
| | | | | | | | | | 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.

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...

* ocfs2: Move directory manipulation code into dir.cMark Fasheh2007-10-125-467/+461
| | | | | | | | | | | | 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: Mark Fasheh <mark.fasheh@oracle.com> Reviewed-by: Joel Becker <joel.becker@oracle.com>
* ocfs2: Small refactor of truncate zeroing codeMark Fasheh2007-10-123-87/+86
| | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * [POWERPC] Use 1TB segmentsPaul Mackerras2007-10-1223-258/+513
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
