Subject: [PATCH] UBI: rename block device ioctls
|
||
|
|
|
||
|
|
Rename the UBI_IOCVOLATTBLK and UBI_IOCVOLDETBLK to UBI_IOCVOLCRBLK and
|
||
|
|
UBI_IOCVOLRMBLK, because we do not use terms "attach" and "detach" for the R/O
|
||
|
|
block devices on top of UBI volumes. Instead, we use terms "create" and
|
||
|
|
"remove". This patch also amends the related commentaries.
