f2fs_inode_info.cp_task was introduced for FS_CP_DATA_IO accounting
since commit b0af6d491a6b ("f2fs: add app/fs io stat").
However, cp_task usage coverage has been increased due to below
commits:
commit 040d2bb318d1 ("f2fs: fix to avoid deadloop if data_flush is on")
commit 186857c5a14a ("f2fs: fix potential recursive call when enabling data_flush")
So that, if data_flush mountoption is on, when data flush was
triggered from background, the IO from data flush will be accounted
as checkpoint IO type incorrectly.
In order to fix this issue, this patch splits cp_task into two:
a) cp_task: used for IO accounting
b) wb_task: used to avoid deadlock
Fixes: 040d2bb318d1 ("f2fs: fix to avoid deadloop if data_flush is on")
Fixes: 186857c5a14a ("f2fs: fix potential recursive call when enabling data_flush")
