[PATCH 1/3] udf: kill udf_set_blocksize

[Christoph Hellwig <hch@lst.de>]

This helper has been quite useless since sb_min_blocksize was introduced
and is misnamed while we're at it.  Just opencode the few lines in the
caller instead.

-/*
- * udf_set_blocksize
- *
- * PURPOSE
- *	Set the block size to be used in all transfers.
- *
- * DESCRIPTION
- *	To allow room for a DMA transfer, it is best to guess big when unsure.
- *	This routine picks 2048 bytes as the blocksize when guessing. This
- *	should be adequate until devices with larger block sizes become common.
- *
- *	Note that the Linux kernel can currently only deal with blocksizes of
- *	512, 1024, 2048, 4096, and 8192 bytes.
- *
- * PRE-CONDITIONS
- *	sb			Pointer to _locked_ superblock.
- *
- * POST-CONDITIONS
- *	sb->s_blocksize		Blocksize.
- *	sb->s_blocksize_bits	log2 of blocksize.
- *	<return>	0	Blocksize is valid.
- *	<return>	1	Blocksize is invalid.
- *
- * HISTORY
- *	July 1, 1997 - Andrew E. Mileski
- *	Written, tested, and released.
