1999-09-13  Roland McGrath  <roland@baalperazim.frob.com>

	* dir.c, truncate.c, pager.c: Reverted changes related to
	io_map_segment.

1999-09-09  Roland McGrath  <roland@baalperazim.frob.com>

	* Makefile (makemode): server -> servers.
	(targets): Replaced with target; remove ext2fs.static.
	(ext2fs.static-LDFLAGS): Variable removed.
	(ext2fs, ext2fs.static): Remove deps.

1999-09-07  Thomas Bushnell, BSG  <tb@mit.edu>

	* dir.c (diskfs_lookup_hard): Pass additional parameter to
	diskfs_get_filemap.
	(diskfs_dirempty): Likewise.
	* truncate.c (force_delayed_copies): Likewise.
	* pager.c (diskfs_get_filemap): Accept additional parameter.

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

	* pager.c (file_pager_write_page): Don't report errors on writes
	that extend past NODE->allocsize.  This avoids a race between sync
	and truncate.  Reported by Mark Kettenis <kettenis@wins.uva.nl>.

1999-08-23  Roland McGrath  <roland@baalperazim.frob.com>

	* ext2_fs.h, ext2_fs_i.h: Replaced with Linux 2.3.14 versions.
	* ext2fs.h (i_mode_high): New macro, missing from ext2_fs.h.

	* inode.c (read_node): Don't set INFO->i_version.
	Extract INFO->i_dir_acl value only for a directory;
	otherwise use zero and instead extract INFO->i_high_size.
	Fail with EFBIG if INFO->i_high_size is nonzero.

	* ialloc.c (diskfs_alloc_node): Propagate initial value of i_flags
	from directory, as Linux 2.3.14 does.

	* inode.c (write_node): Get i_flags from NP->dn->info instead of from
	the disk inode, so we can have modified the in-core version.
	* dir.c (diskfs_direnter_hard, diskfs_dirremove_hard,
	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.

	* balloc.c (ext2_free_blocks): Handle freeing across group boundary,
	as Linux 2.3.14 does.

	* balloc.c (ext2_check_blocks_bitmap): If RO_COMPAT_SPARSE_SUPER
	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.
	(ext2_file_type): New static const variable.
	(diskfs_get_directs): Set d_type member based on file_type field in
	directory entry.

	* balloc.c (ext2_new_block): Take new arg PREALLOC_GOAL.
	Use that instead of hard-coded 8 as maximum of blocks to preallocate.
	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.
	* inode.c (diskfs_set_translator): Pass new arg (zero).

1999-07-11  Roland McGrath  <roland@baalperazim.frob.com>

	* dir.c (diskfs_get_directs): Fix sloppy bugs in last change.
	* hyper.c (allocate_mod_map): Likewise.
	* pager.c (get_page_buf): Likewise.

1999-07-10  Roland McGrath  <roland@baalperazim.frob.com>

	* ext2fs.h: Add #include <sys/mman.h> for munmap decl.

1999-07-06  Thomas Bushnell, BSG  <tb@mit.edu>

	* dir.c (diskfs_get_directs): Use mmap instead of vm_allocate.
	* hyper.c (allocate_mod_map): Likewise.
	(get_hypermetadata): Likewise.
	* pager.c (get_page_buf): Likewise.

	* hyper.c (diskfs_readonly_changed): Use mprotect instead of
	vm_protect.

1999-07-03  Thomas Bushnell, BSG  <tb@mit.edu>

	* dir.c (diskfs_lookup_hard): Use munmap instead of vm_deallocate.
	(diskfs_direnter_hard): Likewise.
	(diskfs_dirremove_hard): Likewise.
	(diskfs_dirrewrite_hard): Likewise.
	(diskfs_dirempty): Likewise.
	(diskfs_drop_dirstat): Likewise.
	(diskfs_get_directs): Likewise.
	* hyper.c (allocate_mod_map): Likewise.
	(get_hypermetadata): Likewise.
	* pager.c (free_page_buf): Likewise.
	* truncate.c (poke_pages): Likewise.

1999-06-29  Thomas Bushnell, BSG  <tb@mit.edu>

	* hyper.c (diskfs_readonly_changed): Adjust whether the store
	should permit writes too.

1999-06-19  Roland McGrath  <roland@baalperazim.frob.com>

	* pager.c (free_page_buf): Fix type cast.

Tue Jun 15 21:51:58 1999  Thomas Bushnell, BSG  <tb@mit.edu>

	* pager.c: Clamp the number of free pages we keep around to some
	reasonably small value.  Patch from Mark Kettenis
	<kettenis@wins.uva.nl>.

1999-06-15  Thomas Bushnell, BSG  <tb@mit.edu>

	* inode.c (diskfs_validate_flags_change): Invert sense of test wrt
	bits that haven't yet been defined.  Reported by Kalle Olavi
