Put the bio when the flush cmd issued, it also can fix the following
kmemleak:
unreferenced object 0x8800270c73c0 (size 200):

Gu Zheng (7):
f2fs: put the bio when issue_flush completed
f2fs: remove the unuseful "issue_tail" list
f2fs: use __GFP_ZERO to avoid appending set-NULL
f2fs: enable flush_merge only in f2fs is not read-only
f2fs: add the flush_merge handle in the remount flow
f2fs: introduce struct flus
With the issue_list and dispatch_list, we can handle flush_merge
already, so remove the useless "issue_tail" list.

Add the *remount* handle of flush_merge option, so that the users
can enable flush_merge in the runtime, such as the underlying device
handles the cache_flush command relatively slowly.

Enable flush_merge only in f2fs is not read-only, so does the mount
option show.

Split the flush_merge fields from sm_i, and use the new struct flush_cmd_control
to wrap it, so that we can igonre these fileds if flush_merge is disable, and
it alse can the structs more neat.
