I needed to test Linux next and it locked up at starting init.
I bisected it down to:
30512d54fae35 ("fs: replace const char* parameter in vfs_statx and do_statx with struct filename")
1e0561928e3ab ("io-uring: Copy path name during prepare stage for statx")
The first commit did not even compile, so I consider the two of the them
the same commit.
Looking at what was changed, I see that the lookup_flags were removed from
the filename_lookup() in the vfs_statx() function, and that the
lookup_flags that were used later on in the function, were never properly
updated either.
