No, it might sync some metadata for other files, but it won't sync their data.

- danudey 6y agoAre you certain? The quote actually says: > With ext4, as a side effect of the filesystem structure, *all pending data and metadata for all file descriptors* will be flushed instead. Is the article mistaken?
- jradd 6y agomanpage suggests the article is not mistaken. `max_batch_time=0` disables batch processing synchronous write operations. the default is 15ms. It seems like a good idea for client filesystem to mount synchronously for data integrity. I'm not aware of i/o being a factor here. Of course this doesn't prevent applications mishandling of file objects.
