* lddbus: Makefile: Declare LDDINC variable earlierLuis Ortega Perez de Villar2013-09-281-2/+3
| | | | | Move the definition of LDDINC earlier into the file. This prevents the following compile time error: lddbus.h: No such file or directory.

| | | | | Don't use create_proc_read_entry() as it is deprecated, but rather use proc_create() and seq_file instead.

* README: update project goal according to realityJavier Martinez Canillas2013-04-271-20/+4
| | | | | | | | | | | | | | | | | | | | | | | | The initial goal of this project was to update the LDD3 example drivers to recent kernels so they can be used by students to learn about driver development under Linux. The idea was to not only update the drivers but also add new drivers that show newer kernel facilities that did not exist (or was not common) by the time the LDD3 book was written. Unfortunately I haven't had time to work on this for years so it's better to just try to keep the current drivers building and working. Also, only maintain the master branch that should track Linus master tree. Anyone that is interested on kernel hacking should develop against the latest master tree anyways. If someone needs to use an older kernel version it shouldn't be hard to figure out what commit id could be used for any specific kernel version.

* tty: update termios access due tty_struct changesJavier Martinez Canillas2013-04-271-2/+2
| | | | | | | | | | commit adc8d746 ("tty: move the termios object into the tty") moved the struct ktermios inside struct tty_struct instead of keeping just a pointer to it. So, let's update the access to termios according to this change. Signed-off-by: Javier Martinez Canillas <javier@dowhile0.org>

* ldd3: get rid of deprecated VM_RESERVED vma flagJavier Martinez Canillas2013-04-265-10/+0
| | | | | | | | | | | | | | commit 314e51b9 ("mm: kill vma flag VM_RESERVED and mm->reserved_vm counter") removed the VM_RESERVED vma flag since it lost original meaning. VM_RESERVED was used on many drivers' mmap function handler to avoid swap this memory area. The same semantic can be specified with VM_IO | VM_DONTDUMP flags but these are already set by remap_pfn_range() so they don't have to be set in drivers mmap function handlers.

| * sbull: Use blk_fetch_request instead blk_peek_request to dequeue requestsJavier Martinez Canillas2011-01-061-9/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The block layer request API changes make a requirement for block drivers to dequeue requests before signal its completition. Commit 1dfd4ab138fc9f9cad869e6110022c7cfd5544d1 changed sbull to use the new block layer API. But the patch only renamed the functions while keeping the old driver semantics. It used blk_peek_request() that does the same that elv_next_request() did. Remove the request from the queue before is not only a recomendation but a true requirement. Attempting to complete a request that remains in the queue make the kernel oops. So the last commit introduced a Bug. This patch uses blk_fetch_request() instead of blk_peek_request(). blk_fetch_request() not only returns the request in the head of the queue but also removes the request from the queue so a latter signaling of the request completition doesn't hang the system.
