Follow-up Comment #9, bug #32472 (project grub):
open_device():
If we use fsync() before close(),
O_SYNC, O_FSYNC should not be used, as it give performance penalty.
When O_SYNC used, every write is blocked until it goes to disk, and fsync()
does nothing.
When O_SYNC is not used, every write is not blocked, but all modified blocks
are written inside fsync(). During fsync(), blocks may be merged, so not using
O_SYNC may significantly improve performance.
So, see attached patch
(file #23191)
