Re: linux-next: Tree for Jan 20 -- Kernel panic - Unable to mount root fs

Hello, Today's linux-next doesn't boot on my qemu VM:

I bisected it down to: 5dc5218840e1 fs: create proper filename objects using getname_kernel() I reverted then reapplied each part of that patch. It works if I leave out the hunk for do_path_lookup: diff --git a/fs/namei.c b/fs/namei.c index eeb3b83661f8..c3d21b79090e 100644 --- a/fs/namei.c +++ b/fs/namei.c @@ -2001,9 +2001,15 @@ static int filename_lookup(int dfd, struct filename *name, static int do_path_lookup(int dfd, const char *name, unsigned int flags, struct nameidata *nd) { - struct filename filename = { .name = name }; + int retval; + struct filename *filename; - return filename_lookup(dfd, &filename, flags, nd); + filename = getname_kernel(name); + if (unlikely(IS_ERR(filename))) + return PTR_ERR(filename); + retval = filename_lookup(dfd, filename, flags, nd); + putname(filename); + return retval; } I don't know what other info you may need.
