* [PATCH] ext4: removesector_t bits checkMingming Cao2006-10-111-6/+4
| | | | | | | | | | | | | | Previously when in-kernel ext4 block type is sector_t, it's only 4 bits long under some 32bit arch (when CONFIG_LBD is not on). So we need to check the size of sector_t before we read 48bit long on-disk blocks to in-kernel blocks. These checks are unnecessary now as we changed the in-kernel blocks to unsigned longlong.

* [PATCH] ext4: 48bit i_file_aclBadari Pulavarty2006-10-111-0/+10
| | | | | | | | | | | | As we are planning to support 48-bit block numbers for ext4, we need to support 48-bit block numbers for extended attributes. In the short term, we can do this by reuse (on-disk) 16-bit padding (linux2.i_pad1 currently used only by "hurd") as high order bits for xattr. This patch basically does that.
