Subject: [PATCH] grub-core: modify sector by sysfs as disk sector
|
||||
|
||||
The disk sector size provided by sysfs file system considers the
|
||||
sector size of 512 irrespective of disk sector size, Thus
|
||||
causing the read by grub to an incorrect offset from what was
|
||||
originally intended.
|
||||
|
||||
Considering the 512 sector size of sysfs data the actual sector
|
||||
needs to be modified corresponding to disk sector size.
