Subject: [PATCH] sadc: Add a -f flag to force fdatasync() use
|
||||
|
||||
For quite some time, the sadc utility has not used fdatasync() when writing
|
||||
stat information to disk. This resulted in instances where data files could
|
||||
be corrupted or entries lost if a system encountered a sudden reset
|
||||
condition. This change adds a "-f" flag which can be used to bring back the
|
||||
previous behaviour if end users require it.
|
||||
|
||||
Note, the fdatasync() lowers the likelihood of lost data, but does so at
|
||||
the expense of performance within the write operation.
