That commit was the fix, not the origin of the bug, so reverting it
was not the right thing to do!

But it's only a fix if your .config has not yet been messed up (with
CONFIG_TMPFS_XATTR and CONFIG_TMPFS_POSIX_ACL unset, though used
somewhere for sound).

So, just delete the CONFIG_TMPFS_XATTR and CONFIG_TMPFS_POSIX_ACL
lines from your .config (perhaps you don't even get an ACL line if the
XATTR is not set, I forget) and run "make oldconfig", this time
choosing Y.

If this was your sound problem too, then the rebuilt kernel should fix it.

Apologies for inflicting this on people: Linus spotted it and got it
fixed up a.s.a.p so it only would only affect those who pulled a tree
yesterday.
