1bcac49c68 scst pr: Use fdatasync() instead of fsync() 
Synchronizing the file contents is sufficient - it is not necessary
to synchronize metadata like atime and mtime after having saved
persistent reservation information.

A more clear explanation of what "datasync" means can be found here
http://linux.die.net/man/2/fdatasync:

<quote>
fdatasync() is similar to fsync(), but does not flush modified metadata
unless that metadata is needed in order to allow a subsequent data
retrieval to be correctly handled. For example, changes to st_atime or
st_mtime (respectively, time of last access and time of last
modification; see stat(2)) do not require flushing because they are not
necessary for a subsequent data read to be handled correctly. On the
other hand, a change to the file size (st_size, as made by say
ftruncate(2)), would require a metadata flush.

The aim of fdatasync() is to reduce disk activity for applications that
do not require all metadata to be synchronized with the disk.
