hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IBNEQX -------------------------------- This reverts commit 0a5788bbf138ca3841a831beed9b9cac729fe46b. Since flags passed by users can not be set to fc->sb_flags, check of fc->sb_flags in nfs_compare_mount_options is useless. The second mount may get the superblock of the first mount since nfs_compare_mount_options will return true, resulting the change of s_flags. Revert this patch and fix the origin issue later.
