<div dir="ltr"><div>Hi,<br>
I am working on a project which requires to implement a file system with<br>
journaling capability.<br>
<br>
While i found a number of simple implementations of file systems , they all<br>
were lacking the journaling capability.<br>
like <a href="https://github.com/raczzoli/testfs" target="_blank">https://github.com/raczzoli/testfs</a> or<br>
<a href="http://hi.baidu.com/yanyulou/item/e31a15f3b559ae49932af287" target="_blank">http://hi.baidu.com/yanyulou/item/e31a15f3b559ae49932af287</a><br>
<br></div>Now that i have implemented the formating procedures for the file system i think the next step would be to implement super_block operations , file operations for the VFS.<br><div>
<br>
I came to know that ext3/ext4 uses a jbd interface which implements the<br>
journaling capability in a file system independent way. But i could not<br>
find any documentation or details for using the jbd interface.<br>
<br>
So, any help which points out to the specific details of jbd interface or<br>
any comments which might be helpful in implementing the journaling<br>
capability is welcome.<br>
