Analyze and fix the following issue in the Linux kernel code: [PATCH] Fix locking for tty drivers when doing urgent characters
Problem Details: If you send a priority character (as is done for flow control) then the tty driver can either have its own method for "jumping the queue" or the characrer can be queued normally. In the latter case we call the write method but without the atomic_write_lock taken elsewhere. Make this consistent. Note...

This happens for files backed by an interruptible NFS mount under nfs_file_flush() when a large file has just been written and nfs...

Problem Details: Address http://bugzilla.kernel.org/show_bug.cgi?id=7126 Attempting to read the ethernet ID directly from the eeprom somehow confuses ADM8515. Subsequent read requests to either the eeprom or the MII fail as well. Didn't dig much deeper, though. For example ADM8513 does not experience this problem. ...
