The adt746x driver currently adds a "°C" suffix to temperatures exposed via sysfs, and I don't like that. First, we all agree that any other unit here makes no sense (do we ? do we ? yes of course :) and I don't like having anything but numbers in there, and finally it's more consistent with what the g5 driver does. And finally, the _REAL_ reason is that this is not a low ASCII character and so has nothing to do in the kernel sources or in /sys :) Unfortunately, generating a patch here is nasty because of that (my mailer is rightfully complaining about the non-ASCII char on text import) so you might have to apply by hand...

There is another (minor) bug that the smp_processor_id() debugger unearthed: diskstats_show() could do a disk_round_stats() -> disk_stat_add() with preemption enabled - possibly resulting in losing statistics updates. Signed-off-by:

If setting the printk log buffer (with the boot command line option "log_buf_len") to a value that's not a power of two, the index calculations go wrong and yield confusing results. This patch rounds the size to the next higher power of two. It'll yield garbage for sizes > INT_MAX bytes. Signed-off-by:

Here's a patch to fix a bug in compat_sys_fcntl64 in fs/compat.c. The bug occurs with a 32 bit app that calls fcntl and checking for a lock near the end of a file. struct flock sflp; sflp.l_start = 2147483345; sflp.l_len = 302; /* 2147483345 + 302 == 2147483647 (this should not overflow 31 bits) */ /* 2^31 == 2147483648 */ fcntl_stat = fcntl(fd, F_GETLK, &sflp); The patch also contains a fix to handle l_len < 0 which is now defined in POSIX 1003.1-2001 from the fcntl man page.

This attached patch adds list_replace_rcu() to include/linux/list.h for atomic updating operations according to RCU-model. void list_replace_rcu(struct list_head *old, struct list_head *new) The 'old' element is detached from the linked list, and the 'new' element is inserted to the same point of the linked list concurrently. This patch is necessary for the performance improvement of SELinux.

reiserfs_set_xattr() explicitly updates the ctime for the host inode. This works for direct setfacl/setfattr calls, but for the more common case of an inherited default ACL, it breaks. The ACL is inherited in the middle of the new inode creation, before the inode has been hashed. When mark_inode_dirty is called, one of the checks bails out if the inode is unhashed -- but AFTER inode->i_state is updated, so the inode is marked dirty but never placed on any dirty list. Since the inode is never placed on a dirty list, __sync_single_inode from the writeback_inodes() path can never be called on it to clear the dirty flags. Once the inode is hashed and mark_inode_dirty is called for it again, it's too late -- it will bail early assuming (correctly) that the inode is already marked dirty. This ultimately results in I/O stalls that can't be resolved by the fs path, only be the memory allocation path that uses pages directly. The attached patch makes the update of the ctime conditional on the inode being hashed already. Signed-off-by:

This patch reaaranges inode_lock taking in writeback_inodes(). It narrows down use of inode_lock and removes unneccassary nesting of sb_lock and inode_lock. Instead of holding inode_lock for all the time I moved it around sync_sb_inodes() as it is in all other places. Signed-Off-By:

This patch fixes race in writeback_inodes() described below: writeback_inodes() { .... sb->s_count++; spin_unlock(&sb_lock); .... spin_lock(&sb_lock); if (__put_super(sb)) <<< X goto restart; } } deactivate_super() { fs->kill_sb(s); kill_block_super(sb) generic_shutdown_super(sb) spin_lock(&sb_lock); list_del(&sb->s_list); <<< Y spin_unlock(&sb_lock); .... put_super(s); spin_lock(&sb_lock); __put_super(sb); <<< Z spin_unlock(&sb_lock); } The problem with it is that writeback_inodes() supposes that if __put_super() returns 0 then no super block was deleted from the list and we can safely traverse sb list further. But as it is obvious from the deactivate_super() it's not actually true. because at point Y we delete super block from the list and drop the lock. We do __put_super() very much later... So we can find sb with poisoned sb->s_list at point X and we won't be the last sb reference holders. The last reference will be dropped in point Z. So in case of the following sequence of execution Y -> X -> Z we'll get an oops after point X in writeback_inodes(). This patch introduces __put_super_and_need_restart() function which allows safe traversing of sb list. I'll send a couple of patches later which remove O(n^2) algos and using this function.

There have been reports of problems running UP ppc64 kernels where the kernel would die in the floating point save/restore code. It turns out kernel threads that call exec (and so become user tasks) do not have a valid thread.regs. This means init (pid 1) does not, it also means anything called out of exec_usermodehelper does not. Once that task has forked (eg init), then the thread.regs in the new task is correctly set. On UP do lazy save/restore of floating point regs. The SLES9 init is doing floating point (the debian version of init appears not to). The lack of thread.regs in init combined with the fact that it does floating point leads to our lazy FP save/restore code blowing up. There were other places where this problem exhibited itself in weird and interesting ways. If a task being exec'ed out of a kernel thread used more than 1MB of stack, it would be terminated due to the checks in arch/ppc64/mm/fault.c (looking for a valid thread.regs when extending the stack). We had a test case using the tux webserver that was failing due to this. Since we zero all registers in ELF_PLAT_INIT, I removed the extra memset in start_thread32. Signed-off-by:

The Spurious interrupt assignment for OpenPIC was the constant, OPENPIC_VEC_SPURIOUS plus the offset passed in. Due to bugs in some OpenPICs, the end value needed to be 255 on those systems. However, the constant was then chosen to be 239, because offset on most systems is 16. The 85xx has an offset of 64, however, and so this assignment caused lock-ups during boot. The proposed solution is to declare OPENPIC_VEC_SPURIOUS to be 255, and use that value directly, instead of adding the offset to it. Signed-off-by:
