Shall I also initialize fsdata here:

$ git grep 'void \*fsdata;'
fs/affs/file.c:         void *fsdata;
fs/ext4/verity.c:               void *fsdata;
fs/f2fs/verity.c:               void *fsdata;
fs/hfs/extent.c:                void *fsdata;
fs/hfsplus/extents.c:           void *fsdata;
fs/ocfs2/mmap.c:        void *fsdata;
