After the recent conversion to the new mount API, there is a warning when building hostfs (which may be upgraded to an error via CONFIG_WERROR=y):
fs/hostfs/hostfs_kern.c: In function 'hostfs_fill_super': fs/hostfs/hostfs_kern.c:942:27: warning: initialization discards 'const' qualifier from pointer target type [-Wdiscarded-qualifiers] 942 | char *host_root = fc->source; | ^~ Add the 'const' qualifier, as host_root will not be modified after its assignment. Move the assignment to keep the existing reverse Christmas tree order intact.
