[Yaffs] read and write operation.cont

Hello!



As mentioned in http://www.yaffs.net/yaffs-porting-guide,
the read/write operation are in yaffs_mtdif.c.

Is it right? Is it the only process or there is another process(with kernel modules for example) too?


Thanks

Subject: read and write operation


Good Day!


I am looking for the serial operations that happen when read and write operation use in a ubuntu system that use yaffs2 as the filesystem.

As I understood, for these operations: os tells to the vfs and the vfs tells to the yaffs to do read or write, then yaffs_file_operations in the yaffs_vfs_multi looks at its structure and call do_sync_read or do_sync_write. these files exist in the kernel and do the read and write operation.

Is there any thing I missing?

Is this sequence explained correctly? If not, would you explain the correct one?



Thanks
