Subject: [PATCH] ext4 filesystem support
Date: Mon, 3 Dec 2012 11:27:44 +0100 [thread overview]
Message-ID: <1354530468-25823-1-git-send-email-s.hauer@pengutronix.de> (raw)
Hi All,
The following adds ext4 readonly filesystem support to barebox.
The implementation is from U-Boot which recently gained ext4
support.
ext filesystems can automatically be detected, so the -t option
to mount is not necessary. Some preparation is needed because
ext filesystems have their magic at byte offset 1080. Currently
we do not pass in such a big buffer into the filesystem detection
code. To fix this we now pass the buffer size to the file detection
code so that we do not read past the buffer.
Sascha

ls command: call stat() only when necessary
filetype: Pass bufsize
add ext fs detection support
fs: implement initial ext4 support from U-Boot
