Subject: [PATCH] ext4: Fix 64bit feature
|
||||
|
||||
As per ext4 specification:
|
||||
|
||||
> In ext2, ext3, and ext4 (when the 64bit feature is not enabled), the
|
||||
> block group descriptor was only 32 bytes long and therefore ends at
|
||||
> bg_checksum. On an ext4 filesystem with the 64bit feature enabled, the
|
||||
> block group descriptor expands to at least the 64 bytes described below;
|
||||
> the size is stored in the superblock.
|
||||
|
||||
Since block group descriptor has been expanded to 64 bytes long (when 64
|
||||
bit feature is enabled), we cannot index ext2_group_desc and return it
|
||||
*directly* -- as we did it in ext2_get_group_desc -- it's still 32 bytes
|
||||
long.
|
||||
|
||||
Instead, use s_desc_size field from superblock to correctly index and
|
||||
return block group descriptors.
