Re: [U-Boot] [PATCH] tools/fw_env: use fsync to ensure that data is physically stored

Dear Michael Heimpold,

In message 1369078482-5863-1-git-send-email-mhei@heimpold.de you wrote:

Closing a file descriptor does not guarantee that the data has been successfully saved to disk, as the kernel might defer the write.

What is the exact problem you are trying to fix?

I mean, when exactly does adding the sync play a role?

Best regards,

Wolfgang Denk
