2014-01-14sound: oss: dmasound: kill SLEEP() macro to avoid raceArnd Bergmann
The use of interruptible_sleep_on_timeout in the dmasound driver is questionable and we want to kill off all sleep_on variants. This replaces the calls with wait_event_interruptible_timeout where possible, to wait for a particular event instead of blocking in a racy way. In the sq_write function, the easiest solution is an open-coded prepare_to_wait loop. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>

2010-09-14sound: autoconvert trivial BKL users to private mutexArnd Bergmann
The usage of the BKL in the OSS sound drivers is trivial, and each of them only locks against itself, so it can be turned into per-driver mutexes. This is the script that was used for the conversion: file=$1 name=$2 if grep -q lock_kernel ${file} ; then if grep -q 'include.*linux.mutex.h' ${file} ; then sed -i '/include.*<linux\/smp_lock.h>/d' ${file} else sed -i 's/include.*<linux\/smp_lock.h>.*$/include <linux\/mutex.h>/g' ${file} fi sed -i ${file} \ -e "/^#include.*linux.mutex.h/,$ { 1,/^\(static\|int\|long\)/ { /^\(static\|int\|long\)/istatic DEFINE_MUTEX(${name}_mutex); } }" \ -e "s/\(un\)*lock_kernel\>[ ]*()/mutex_\1lock(\&${name}_mutex)/g" \ -e '/[ ]*cycle_kernel_lock();/d' else sed -i -e '/include.*\<smp_lock.h\>/d' ${file} \ -e '/cycle_kernel_lock()/d' fi Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>

2010-07-12sound: push BKL into open functionsArnd Bergmann
This moves the lock_kernel() call from soundcore_open to the individual OSS device drivers, where we can deal with it one driver at a time if needed, or just kill off the drivers. All core components in ALSA already provide adequate locking in their open()-functions and do not require the big kernel lock, so there is no need to add the BKL there.

2008-11-01oss: fix O_NONBLOCK in dmasound_coreAl Viro
We broke O_NONBLOCK handling in OSS dmasound_core in 2.3.11-pre3 - the original code copied f_flags to open_mode and then checked for O_NONBLOCK in there, but that got changed to copying f_mode and O_NONBLOCK has not reached that field in any kernel version. Since we do not care for any other bits, the fix is obvious... Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2007-02-12[PATCH] mark struct file_operations const 9Arjan van de Ven
Many struct file_operations in the kernel can be "const". Marking them const moves these to the .rodata section, which avoids false sharing with potential dirty data. In addition it'll catch accidental writes at compile time to these shared resources.

2005-04-16Linux-2.6.12-rc2Linus Torvalds
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
