Subject: why clear_buffer_uptodate in end_buffer_write_sync on write error?
Date: Sun, 02 Jan 2005 21:18:28 -0500	[thread overview]
Message-ID: <41D8AB74.7010409@sbcglobal.net> (raw)

I'm trying to understand the file systems.  I'm making good progress, 
but I don't get this.  If the buffer is marked not up to date because 
the write failed, won't this cause block_prepare_write to try and read 
the buffer using ll_rw_block thereby overwriting the data that couldn't 
be written?  Is this desirable?  Perhaps I'm confused?
