1c002e1049 fs/vfs/fs_fstat: Correct fstat() for proxied block and MTD drivers.
Block and MTD drivers may be opened and managed as though they were character drivers.  But this is really sleight of hand; there is a hidden character driver proxy that mediates the interface to the block and MTD drivers in this case.

fstat(), however, did not account for this.  It would report the characteristics of the proxy character driver, not of the underlying block or MTD driver.

This change corrects that.  fstat now checks if the character driver is such a proxy and, if so, reports the characteristics of the underlying block or MTD driver, not the proxy character driver.

dd9d9878ad fs/vfs/fs_stat.c: fill file size for mtd inode
Now when stat() is calling for mtd device it also set size of file as number of bytes of all sectors related to this mtd device.

8f2c7198ed inode_find: Now takes struct inode_desc_s type as input. This was necessary before that structure includes some data storage. It was used within inode_find(), but that means that the life of the data was the life of inode_find(). That data must persist longer. It is now provided by the caller so that the life of the data persists for the entire life of the caller. 2017-02-05 09:51:42 -06:00
