* bitmap.c (ffz): Subtract one from (1-origin) result of ffs to get our (0-origin) result. * Makefile (LCLHDRS): bitmap.h -> bitmap.c
1999-10-031999-10-03 Roland McGrath <roland@baalperazim.frob.com>Roland McGrath
* ext2fs.h (test_bit, set_bit, clear_bit): Rewritten to operate on 32-bit words instead of bytes. * ext2fs.h (group_desc): Inline function replaced with macro. (group_desc_image): New variable. * hyper.c (get_hypermetadata): Initialize it. * ext2fs.h (sblock_block): Declare new variable. (SBLOCK_LBLOCK): Macro removed. (SBLOCK_OFFS): Define in terms of sblock_block. * ext2fs.c (options): Add --sblock/-S. (parse_opt): Parse it to set sblock_block. * hyper.c (sblock_block): New variable. (get_hypermetadata): Use sblock_block instead of constant SBLOCK_BLOCK. * hyper.c (get_hypermetadata): Use EXT2_MAX_BLOCK_SIZE instead of 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. (BLOCKSIZE_SCALE): Just use SBLOCK->s_log_block_size directly. * hyper.c (get_hypermetadata): Fix printf formats to silence warning. * dir.c (dirscanblock): Likewise.

* dir.c (file_type_ext2): New const variable, map DT_* -> EXT2_FT_*. (diskfs_direnter_hard): Move initialization of directory entry content fields out of switch; use memcpy or memmove as appropriate, instead of 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.
1999-10-031999-10-03 Roland McGrath <roland@baalperazim.frob.com>Roland McGrath

* ext2fs.h (SBLOCK_LBLOCK): New macro, filesystem block number of sb. (BLOCKSIZE_SCALE): New macro for converting min-blocks to fs blocks. (group_desc): Fix calculation of offset from superblock, so it works properly with block_size != EXT2_MIN_BLOCK_SIZE. * ext2fs.h (EXT2FS_EI): New macro, use it for all extern inlines.

* 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. * 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).
1999-08-231999-08-23 Roland McGrath <roland@baalperazim.frob.com>Roland McGrath
* 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. * 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_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).
1999-08-231999-08-23 Roland McGrath <roland@baalperazim.frob.com>Roland McGrath
* ialloc.c (diskfs_alloc_node): Propagate initial value of i_flags from directory, as Linux 2.3.14 does.
1999-08-231999-08-23 Roland McGrath <roland@baalperazim.frob.com>Roland McGrath
* ext2_fs.h, ext2_fs_i.h: Replaced with Linux 2.3.14 versions. * ext2fs.h (i_mode_high): New macro, missing from ext_fs.h.

(ext2_file_type): New static const variable. (diskfs_get_directs): Set d_type member based on file_type field in directory entry.
