Kernel

2.6.36/37 suggestion
In reply to Ted Tso (http://article.gmane.org/gmane.linux.kernel/1008643) I would like to suggest kernel developers (first of all, Linus) some kind of compromise. Let's prohibit accepting new features during 2.6.36 merge window and accept only bugfixes until bugzilla and regression lists are empty. For drivers sub... 29 Jul 2010 11:53

Hi, I am currently working on a stackable filesystem and would like to implement memory mapping for it. I have looked at the ecryptfs way of doing this and wonder if this really has to be that complicated (create a persistent file for each inode, start a kernel thread only to handle requests to open those pe... 29 Jul 2010 10:47

[PATCH] cris: gpio: do not call copy_to_user()/copy_from_user() while holding spinlocks

[bug] Fixing mutex_lock() under held spinlock
Hi, I've found that cfi_cmdset and lpddr_cmds call mutex_lock() under held spinlock(). Maybe it was designed as a special locking scheme, so I don't try to fix it as I might create new complex locking problem. --- ./drivers/mtd/chips/cfi_cmdset_0001.c 2010-07-06 16:45:43.000000000 +0400 +++ /tmp/cocci-output... 29 Jul 2010 09:41
