Clone STORE before remapping it.
Rewritten to use store functions.

find_block, pager_unlock_page, diskfs_grow):
Use store_ operations instead of the old device ones, and some store
fields instead of globals.
(file_pager_read_page):
Make BUF void **, NEW_BUF void *, and LENGTH size_t.
Pass &LENGTH to store_read, not LENGTH.
(free_page_bufs, free_page_bufs_lock):
New variables.
(create_disk_pager):
Create PAGER_BUCKET.
Pass in new args to diskfs_pager_setup (renamed from disk_pager_setup).

Function removed.
(struct pending_blocks):
Make BUF void *.
(disk_pager_write_page):
Make BUF void *, and LENGTH size_t.
Check amount written, and return EIO if it's wrong.

New variable.
(get_page_buf, free_page_buf):
New functions.
(disk_pager_read_page):
Make BUF void **, and LENGTH size_t.

Use filesystem blocks, not device blocks, in block<->offset/size
conversions.

Make PAGE_BUF void *, and LENGTH size_t.
Check amount written, and return EIO if it's wrong.

When setting ds->stat to EXTEND, set ds->idx by looking at the size of the
file.
After successful dirscanblock, record index where we finished in
DP->dn->dir_idx.
Start searches at that index.
(dirscanblock): Size dirents correctly when mallocing it.
(diskfs_direnter_hard):
Be more careful when sizing or resizing dirents.
Correctly set to -1 all the new entries we create after realloc call.
(diskfs_direnter_hard): Initialize OLDSIZE to quiet gcc.
|
|
|
|
(file_pager_read_page): Use free_page_buf to deallocate pages.

(as linux apparently does this sometimes with devices).
|
|
assert that st_blocks == 0 for any case where we set allocsize to 0.
|
|
(diskfs_version_extra): New variable.
|
|
|
|
(ext2_debug): redefine macro after including ext2_fs.h.
|
|
Use EXT2_INODE_SIZE instead of sizeof (struct ext2_inode).
Deal with various version 2.x features.
|
|
Pass SBLOCK as a parameter to EXT2_FIRST_INO (v2.x change).
|
|
|
|
|
|
|

All uses of these types changed to have a leading `__'.
