Since commit e7bed0b5bc4b, toggling FS_XFLAG_DAX on an existing file can make
S_DAX on the file change immediately when all applications close the file.
As a result, we don't need the redundant drop cache and umount & mount cycle.

Write data into a file and then enable DAX on the file immediately,
the written data which is still in the buffer will be lost when
the corresponding inode is evicted.

It's a regression test for commit 26b15a042b8a.

This and the comment below are confusing.  Doesn't the buffered data get
written?  Which means the data is not lost?

IOW the test is checking to make sure the data does not get lost, not that it
does.  What am I missing?

Hi Ira,

Thanks for your quick comment.

How about the following commit message:
-------------------------------------------------------------------------

Write data into a file and then enable DAX on the file immediately,
the written data which is still in the buffer should be synchronized
to disk instead of discarded when the corresponding inode is evicted.

-------------------------------------------------------------------------
> IOW the test is checking to make sure the data does not get lost, not that it
> does.  What am I missing?

Right, the data should not get lost.

Xiao Yang

Hi All,

Sorry for the wrong commit ids on the v2 patchset.
I will correct them on v3 patchset soon.
