xfs: cleanup xfs_bmap.h

Convert all function prototypes to the short form used elsewhere,
and remove duplicates of comments already placed at the function
body.

xfs: move firstblock and bmap freelist cursor into bmalloca structure

2011-10-12T02:15:05+00:00

Rather than passing the firstblock and freelist structure around,
embed it into the bmalloca structure and remove it from the function
parameters.

This also enables the minleft parameter to be set only once in
xfs_bmapi_write(), and the freelist cursor directly queried in
xfs_bmapi_allocate to clear it when the lowspace algorithm is
activated.

xfs: move extent records into bmalloca structure

2011-10-12T02:15:05+00:00

Rather that putting extent records on the stack and then pointing to
them in the bmalloca structure which is in the same stack frame, put
the extent records directly in the bmalloca structure. This reduces
the number of args that need to be passed around.

xfs: rename xfs_bmapi to xfs_bmapi_write

2011-10-12T02:15:04+00:00

Now that all the read-only users of xfs_bmapi have been converted to
use xfs_bmapi_read(), we can remove all the read-only handling cases
from xfs_bmapi().

Once this is done, rename xfs_bmapi to xfs_bmapi_write to reflect
the fact it is for allocation only. This enables us to kill the
XFS_BMAPI_WRITE flag as well.

Also clean up xfs_bmapi_write to the style used in the newly added
xfs_bmapi_read/delay functions.

xfs: introduce xfs_bmapi_delay()

2011-10-12T02:15:04+00:00

Delalloc reservations are much simpler than allocations, so give
them a separate bmapi-level interface.  Using the previously added
xfs_bmapi_reserve_delalloc we get a function that is only minimally
more complicated than xfs_bmapi_read, which is far from the complexity
in xfs_bmapi.  Also remove the XFS_BMAPI_DELAY code after switching
over the only user to xfs_bmapi_delay.

xfs: remove xfs_bmapi_single()

2011-10-12T02:15:03+00:00

Now we have xfs_bmapi_read, there is no need for xfs_bmapi_single().
Change the remaining caller over and kill the function.
