* 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>.

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

* 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).

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).
* 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.
