Hi Mike,

I too had this same issue. Below is a quote from what I found and how I got it compiling. I am still waiting for a developer response, as I wanted to make sure the correct information gets passed to the function.

My thread was titled "Current Yaffs2 Compilation Bugs with Some Fixes" and here is what I found:

>> Compilation broke on commit: 30f956c32c235e6b5fa77fb29965ababbd497561,

>> Here are the following that have been missed that discard parameter:

Hello,

I'm trying to compile latest yaffs2 version from git but I'm getting these errors:
fs/yaffs2/yaffs_vfs.c: In function 'yaffs_file_flush':
fs/yaffs2/yaffs_vfs.c:741: error: too few arguments to function 'yaffs_flush_file'
fs/yaffs2/yaffs_vfs.c: In function 'yaffs_sync_object':
fs/yaffs2/yaffs_vfs.c:771: error: too few arguments to function 'yaffs_flush_file'
fs/yaffs2/yaffs_vfs.c: In function 'yaffs_flush_inodes':
fs/yaffs2/yaffs_vfs.c:2190: error: too few arguments to function 'yaffs_flush_file'
fs/yaffs2/yaffs_vfs.c: In function 'yaffs_flush_super':
fs/yaffs2/yaffs_vfs.c:2203: error: too few arguments to function 'yaffs_flush_whole_cache'

I see that yaffs_vfs.c is out of sync with yaffs_guts but I'm unsure how to fix it properly.

Please advise. Thank you!

Best regards,
Mike
