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.
