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>

/*
|

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

||||
* Reservation functions here avoid a huge stack in xfs_trans_init due to
|
||||
