    ext4: Automatically allocate delay allocated blocks on close · 7d8f9f7d
    Theodore Ts'o 提交于
    When closing a file that had been previously truncated, force any
    delay allocated blocks that to be allocated so that if the filesystem
    is mounted with data=ordered, the data blocks will be pushed out to
    disk along with the journal commit.  Many application programs expect
    this, so we do this to avoid zero length files if the system crashes
    unexpectedly.
