Subject: [PATCH] FAT: Support synchronous updates
Date: Sun, 06 Mar 2005 09:07:01 +0900 [thread overview]
Message-ID: <87br9x8wnu.fsf_-_@devron.myhome.or.jp> (raw)
In-Reply-To: <87hdjqrl44.fsf@devron.myhome.or.jp> (OGAWA Hirofumi's message of "Sun, 06 Mar 2005 03:41:31 +0900")

received duplicated email, sorry.]
Hi,
These patches adds the `-o sync' and `-o dirsync' supports to fatfs.
If user specified that option, the fatfs does traditional ordered
updates by using synchronous writes. If compared to before, these
patches will show a improvement of robustness I think.
`-o sync' - writes all buffers out before returning from syscall.
`-o dirsync' - writes the directory's metadata, and unreferencing
operations of data block.
remaining to be done
fat_generic_ioctl(), fat_notify_change(),
ATTR_ARCH of fat_xxx_write[v],
and probably, filling hole in cont_prepare_write(),
NOTE: Since fatfs doesn't have link-count, unfortunately ->rename() is
not safe order at all. It may make the shared blocks, but user
shouldn't lose the data by ->rename().
Please apply.
