mainline-inclusion from mainline-v5.13-rc4 commit 9d5ee837595134f91bb2d66f571f498c3b8ab148 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I4KIAO CVE: NA
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i...
-------------------------------------------------
Pass a pointer to the actual eofb structure around the inode scanner functions instead of a void pointer, now that none of the functions is used as a callback.
