Subject: f2fs: do not recover i_size if it's valid
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=3a3a5ead7b6d2c9a29f493791ba23f264052db34;p=linux-beck.git

f2fs: do not recover i_size if it's valid

If i_size is already valid during roll_forward recovery, we should not update
it according to the block alignment.
