1999-10-06  Roland McGrath  <roland@baalperazim.frob.com>

	* hyper.c (get_hypermetadata): Avoid overflow in calculation of disk
	size vs superblock-specified requirement.
	Add a warning for wasted disk blocks after last filesystem block.

1999-10-03  Roland McGrath  <roland@baalperazim.frob.com>

	* dir.c (ext2_file_type): #if 0 out this variable.
	(diskfs_get_directs): #if 0 out code to interpret file_type field
	and set d_type.  Instead, always return DT_UNKNOWN for now.

	* dir.c (file_type_ext2): #if 0 out.
	(diskfs_direnter_hard): #if 0 out code to set file_type field in
	directory entries.  Instead, always set it to zero.

1999-10-03  Roland McGrath  <roland@baalperazim.frob.com>

	* bitmap.c (ffz): Subtract one from (1-origin) result of ffs to get
	our (0-origin) result.

	* Makefile (LCLHDRS): bitmap.h -> bitmap.c

	* ext2fs.h (test_bit, set_bit, clear_bit): Rewritten to operate on
	32-bit words instead of bytes.

	* truncate.c (diskfs_truncate): Add missing call to
	diskfs_end_catch_exception.

	hard-wired 8192.  Don't use ffs to compute log2_block_size, and don't
	check for the impossible case of non-power-of-two block size (the
	block size specification we start with is given as a power of two!).
	* ext2fs.h (block_size): Change type to unsigned int.

	bcopy.  Set file_type field in new directory entry to appropriate
	type for the node, or to zero if the filesystem doesn't have the
	EXT2_FEATURE_INCOMPAT_FILETYPE flag set.

1999-10-02  Roland McGrath  <roland@baalperazim.frob.com>

	* ext2fs.h (SBLOCK_LBLOCK): New macro, filesystem block number of sb.

	properly with block_size != EXT2_MIN_BLOCK_SIZE.

	* pager.c (diskfs_get_filemap): Accept additional parameter.

1999-09-04  Thomas Bushnell, BSG  <tb@mit.edu>

	and truncate.  Reported by Mark Kettenis <kettenis@wins.uva.nl>.

	diskfs_dirrewrite_hard): Clear EXT2_BTREE_FL flag bit from
	DP->dn->info.i_flags after modifying the directory (this is what
	Linux 2.3.14 does).

	* inode.c (read_node): i_version -> i_generation
	* inode.c (write_node): Likewise.

	feature flag is set, or if group number is not a power of 3, 5, or 7
	(I don't know why; this is what Linux 2.3.14 does), skip tests for
	superblocks and descriptor blocks being free in bitmap.

	* dir.c: Replace `struct ext2_dir_entry' with `struct ext2_dir_entry_2'
	in all uses.

	directory entry.

	* balloc.c (ext2_new_block): Take new arg PREALLOC_GOAL.

	Also test that instead of PREALLOC_COUNT to decide whether to
	try any preallocation at all.
	* getblk.c (ext2_alloc_block): Pass new arg to ext2_new_block.
	Use EXT2_DEFAULT_PREALLOC_BLOCKS as default (replaces hard-coded 8);
	For a regular file, use SBLOCK->s_prealloc_blocks before default.
	For a directory, use SBLOCK->s_dir_prealloc_blocks if the
	EXT2_FEATURE_COMPAT_DIR_PREALLOC flag is set, otherwise zero.
