Subject: UBI: introduce UBI_ALL constant
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=05a3cb7dcec5a15ed9b18a5317ba2075355c7547;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

UBI: introduce UBI_ALL constant

Joel will use it in his 'ubi_flush()' extention to specify all eraseblocks.
Also amend the comment for UBI_UNKNOWN - it is used beyond attaching info
structure now.
