Use kernel macros and functions for timer encapsulation -- do not access fileds directly. Also del_timer on inactive is legal, so that noting if it runs is senseless, delete these variables. Signed-off-by:

moxaXmitBuff is almost unused -- only one byte from the whole PAGE_SIZE bytes is used. Do not alloc so much space for almost anything. Also remove lock protecting this page allocation. Signed-off-by:

Allow taint flags to be set from userspace by writing to /proc/sys/kernel/tainted, and add a new taint flag, TAINT_USER, to be used when userspace has potentially done something dangerous that might compromise the kernel. This will allow support personnel to ask further questions about what may have caused the user taint flag to have been set. For example, they might examine the logs of the realtime JVM to see if the Java program has used the really silly, stupid, dangerous, and completely-non-portable direct access to physical memory feature which MUST be implemented according to the Real-Time Specification for Java (RTSJ). Sigh. What were those silly people at Sun thinking? [akpm@osdl.org: build fix] [bunk@stusta.de: cleanup] Signed-off-by:

driver_data are initialzed to NULL from tty layer, no need to do it in the driver. In this case it cases oops, since driver_data may be NULL for a short while for another closing process. Signed-off-by:

Because brd->info is not NULLed, resources are released twice. NULL it in pci_remove function. Also take care of retval and releasing in pci_probe -- mxser_initbrd alreasy releases resource, do not do it again in fail path in probe function. Cc: Sergei Organov <osv@javad.com> Signed-off-by:

Avoid oopsing when stress-testing open/close -- port->tty is NULL sometimes, but is expected to be non-NULL, since dereferencing. Receive/transmit chars iff ASYNC_CLOSING is not set and ASYNC_INITIALIZED is set. Thanks Sergei for pointing this out and testing. Cc: Sergei Organov <osv@javad.com> Signed-off-by:

Isicom driver no longer registers chardev with ioctl function. It used to use for firmware loading. Remove the reserved letter (M) from ioctl-number, so that the conflict get away. Signed-off-by:

The PNP framework doesn't export "pnp_bus_type", which is an unfortunate exception to the policy followed by pretty much every other bus. I noticed this when I had to find a device in order to provide its platform_data. Note that per advice from Arjan, the "export" scope has been been minimized to avoid the hundred-plus bytes needed to support access from modules. In this case, the symbol is only needed by statically linked kernel code that lives outside the drivers/pnp directory. Signed-off-by:

This one was pointed out on the MOKB site: http://kernelfun.blogspot.com/2006/11/mokb-09-11-2006-linux-26x-ext2checkpage.html If a directory's i_size is corrupted, ext2_find_entry() will keep processing pages until the i_size is reached, even if there are no more blocks associated with the directory inode. This patch puts in some minimal sanity-checking so that we don't keep checking pages (and issuing errors) if we know there can be no more data to read, based on the block count of the directory inode. This is somewhat similar in approach to the ext3 patch I sent earlier this year. Signed-off-by:

Mathieu Desnoyers authored
Mathieu originally needed to add this for tracing Xen, but it's something that's needed for any application that can be tracing while cpus are added. unplug isn't supported by this patch. The thought was that at minumum a new buffer needs to be added when a cpu comes up, but it wasn't worth the effort to remove buffers on cpu down since they'd be freed soon anyway when the channel was closed.

Userspace should be worrying about userspace, so having the socket.h and stat.h pollute the namespace in the non-glibc case is wrong and pretty much prevents any other libc from utilizing these headers sanely unless they set up the __GLIBC__ define themselves (which sucks) Cc: "David S.

The line discipline numbers N_* are currently defined for each architecture individually, but (except for a seeming mistake) identically, in asm/termios.h. There is no obvious reason why these numbers should be architecture specific, nor any apparent relationship with the termios structure. The total number of these, NR_LDISCS, is defined in linux/tty.h anyway. So I propose the following patch which moves the definitions of the individual line disciplines to linux/tty.h too. Three of these numbers (N_MASC, N_PROFIBUS_FDL, and N_SMSBLOCK) are unused in the current kernel, but the patch still keeps the complete set in case there are plans to use them yet. Signed-off-by:

When igrab() is calling __iget() on an inode it should check if clear_inode() has been called on the inode already. Otherwise there is a race window between clear_inode() and destroy_inode() where igrab() calls __iget() which leads to already free inodes on the inode lists. Signed-off-by:

- returns after DEBUG_LOCKS_WARN_ON added in 3 places - debug_locks checking after lookup_chain_cache() added in __lock_acquire() - locking for testing and changing global variable max_lockdep_depth added in __lock_acquire() From: Ingo Molnar <mingo@elte.hu> My __acquire_lock() cleanup introduced a locking bug: on SMP systems we'd release a non-owned graph lock. Fix this by moving the graph unlock back, and by leaving the max_lockdep_depth variable update possibly racy. (we dont care, it's just statistics) Also add some minimal debugging code to graph_unlock()/graph_lock(), which caught this locking bug. Signed-off-by:
