hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IB42W1 -------------------------------- Commit 573573887e0b ("nfs: pass flags to second superblock") directly assigns fc->sb_flags to dentry->d_sb->s_flags, which will cause the loss of the initialized flags in dentry->d_sb->s_flags. Fix it by just passing SB_RDONLY from fc->sb_flags to dentry->d_sb->s_flags.
