Subject[PATCH 2/3] f2fs: fix to wait all atomic written pages writeback
Message-ID<pNaKC-2i1-17@gated-at.bofh.it>
This patch fixes the incorrect range (0, LONG_MAX) which is used
in ranged fsync. If we use LONG_MAX as the parameter for indicating
the end of file we want to synchronize, in 32-bits architecture
machine, these datas after 4GB offset may not be persisted in
storage after ->fsync returned.

Here, we alter LONG_MAX to LLONG_MAX to fix this issue.
