You could do both. Have the x86 directory that Linus suggests for shared

Symlinks are usually a bad idea because they tend to not work with objdirs.

Ok,
If bytes get lost in the communication with a serial mouse using the
MS protocol, the kernel driver could do a better job getting back in
sync. The first byte in a packet has bit 6 set, and no other bytes
have that bit set. Therefore, if a byte is received with bit 6 cleared

This patch introduces a separate hashtable per process to store _PRIVATE
futexes.
This hashtable is dynamically allocated on the first _PRIVATE futex syscall.
If memory cannot be allocated, the process will use the global

Radix trees' space behavior is extremely poor in sparsely-populated

What does this mean?
pgd are not completely zeroed. They contain mappings that are always
present. Thus the state is not a zeroed state.

I'm guessing that the pthread stacks are mmap'ed as greatest extents

Please all, forget about MAP_GROWSDOWN.

Because the command line is increased to 2048 characters after 2.6.21,
it's not possible for boot loaders and userspace tools to determine the length
of the command line the kernel can understand. The benefit of knowing the
length is that users can be warned if the command line size is too long
Gerd The console subsystem already has an idea of a boot console,
