Linus Torvalds b59eea554f vfs: fix flock compat thinko ... Michael Ellerman reported that commit 8c6657cb50 ("Switch flock copyin/copyout primitives to copy_{from,to}_user()") broke his networking on a bunch of PPC machines (64-bit kernel, 32-bit userspace). The reason is a brown-paper bug by that commit, which had the arguments to "copy_flock_fields()" in the wrong order, breaking the compat handling for file locking. Apparently very few people run 32-bit user space on x86 any more, so the PPC people got the honor of noticing this "feature". Michael also sent a minimal diff that just changed the order of the arguments in that macro. This is not that minimal diff. This not only changes the order of the arguments in the macro, it also changes them to be pointers (to be consistent with all the other uses of those pointers), and makes the functions that do all of this also have the proper "const" attribution on the source pointers in order to make issues like that (using the source as a destination) be really obvious.
