xfs: cleanup log reservation calculactions
Instead of having small helper functions calling big macros do the calculations for the log reservations directly in the functions. These are mostly 1:1 from the macros execept that the macros kept the quota calculations in their callers. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Alex Elder <aelder@sgi.com>

52 * Reservation functions here avoid a huge stack in xfs_trans_init 53 * Various log reservation values.
53 * due to register overflow from temporaries in the calculations. 54 *
55 * These are based on the size of the file system block because that is what
56 * most transactions manipulate. Each adds in an additional 128 bytes per
57 * item logged to try to account for the overhead of the transaction mechanism.
58 *
59 * Note: Most of the reservations underestimate the number of allocation
60 * groups into which they could free extents in the xfs_bmap_finish() call.
61 * This is because the number in the worst case is quite high and quite
62 * unusual. In order to fix this we need to change xfs_bmap_finish() to free
63 * extents in only a single AG at a time. This will require changes to the
64 * EFI code as well, however, so that the EFI for the extents not freed is
65 * logged again in each transaction. See SGI PV #261917.
