Subject: [PATCH 1/6] f2fs: delete obsolete FI_FIRST_BLOCK_WRITTEN
Commit 3c6c2bebef79 ("f2fs: avoid punch_hole overhead when releasing
volatile data") introduced FI_FIRST_BLOCK_WRITTEN as below reason:
This patch is to avoid some punch_hole overhead when releasing volatile
data. If volatile data was not written yet, we just can make the first
page as zero.
After commit 7bc155fec5b3 ("f2fs: kill volatile write support"), we
won't support volatile write, but it missed to remove obsolete
FI_FIRST_BLOCK_WRITTEN, delete it in this patch.
