In commit e6bafba5, a bug was fixed that involved converting !x & y to !(x & y). The code below shows the same pattern, and thus should perhaps be fixed in the same way. This is not tested and clearly changes the semantics, so it is only something to consider. The semantic patch that makes this change is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ expression E1,E2; @@ ( !E1 & !E2 | - !E1 & E2 + !(E1 & E2) ) // </smpl> Signed-off-by:

As the result of a previous change that delayed the loading of the firmware, the driver can sometimes report a bogus error regarding the yuv output filter table not being found in the firmware. This patch moves the filter table check to ensure it's only done after the firmware has been loaded. Signed-off-by:

unsigned long != __le32, TYVM, and unsigned char[4] is not guaranteed to be aligned for u32. While we are at it, sanitize sOutDW() a bit - have it take Byte_t * and handle dereferencing internally. NB: sWriteTxPrioByte() is almost certainly buggered on big-endian and is missing cpu_to_le16() on assignments to *WordPtr; I've left it alone for now. Signed-off-by:

Implement support for the E-Ink Metronome controller. It provides an mmapable interface to the controller using defio support. It was tested with a gumstix pxa255 with Vizplex media using Xfbdev and various X clients such as xeyes, xpdf, xloadimage. This patch also fixes the following bug: Defio would cause a hang on write access to the framebuffer as the page fault would be called ad-infinitum. It fixes fb_defio by setting the mapping to be used by page_mkclean. Signed-off-by:

In the process of writing up the mechanical proof of correctness for the dynticks/preemptable-RCU interface, I noticed misplaced memory barriers in rcu_enter_nohz() and rcu_exit_nohz(). This patch puts them in the right place and adds a comment. The key thing to keep in mind is that rcu_enter_nohz() is -exiting- the mode that can legally execute RCU read-side critical sections. The memory barrier must be between any potential RCU read-side critical sections and the increment of the per-CPU dynticks_progress_counter, and thus must come -before- this increment. And vice versa for rcu_exit_nohz(). The locking in the scheduler is probably saving us for the moment. Also, switch to smp_mb() - we don't need a barrier for uniprocessor kernels. Signed-off-by:

Since 4c7ffe0b ("fbdev: prevent drivers that have hardware cursors from calling software cursor code") every call of i810fb_cursor fails with -ENXIO because of a incorrect "!". This hasn't struck until eaa0ff15 ("fix ! versus & precedence in various places") surrounded the expression with braces, so that the intended behavior was inverted. That caused 'pixel waste' - the same line of multi-colored pixels repeated over the whole screen - during console switch. This switches back to the original pre-4c7ffe0b behavior. Signed-off-by:

Fix a long-standing typo (predating git) that will cause data corruption if a journal data block needs unescaping. At the moment the wrong buffer head's data is being unescaped. To test this case mount a filesystem with data=journal, start creating and deleting a bunch of files containing only JBD2_MAGIC_NUMBER (0xc03b3998), then pull the plug on the device. Without this patch the files will contain zeros instead of the correct data after recovery. Signed-off-by:

In the SYSV ipc msgctl(),semctl(),shmctl() family, if the user passed *_INFO as the desired operation, no specific object is meant to be controlled and only system-wide information is returned. This leads to a NULL IPC object in the LSM hooks if the _INFO flag is given. Avoid dereferencing this NULL pointer in Smack ipc *ctl() methods. Signed-off-by:

Fix up an error in iget removal in which romfs_lookup() making a successful call to romfs_iget() continues through the negative/error handling (previously the successful case jumped around the negative/error handling case): (1) inode is initialised to NULL at the top of the function, eliminating the need for specific negative-inode handling. This means the positive success handling now flows straight through. (2) Rename the labels to be clearer about what they mean. Also make romfs_lookup()'s result variable of type long so as to avoid 32-bit/64-bit conversions with PTR_ERR() and friends. Based upon a report and patch from Adam Richter.

The check t->pid == t->pid is not the blessed way to check whether a task is a group leader. This is not about the code beautifulness only, but about pid namespaces fixes - both the tgid and the pid fields on the task_struct are (slowly :( ) becoming deprecated. Besides, the thread_group_leader() macro makes only one dereference :) Signed-off-by:
