Subject: nilfs2: remove meaningless EBUSY case from nilfs_get_sb function
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=81fc20bd0e75ba6357bce2403767d7c2585d8f28;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

nilfs2: remove meaningless EBUSY case from nilfs_get_sb function

The following EBUSY case in nilfs_get_sb() is meaningless.  Indeed,
this error code is never returned to the caller.

    if (!s->s_root) {
          ...
    } else if (!(s->s_flags & MS_RDONLY)) {
        err = -EBUSY;
    }

This simply removes the else case.
