    SubjectRe: [RFC PATCH 0/2] Union Mount: Directory listing in glibc
    Date

    Hello Nagabhushan,

    bsn.0007@gmail.com:
    > I went through Bharata's RFC post on glibc based Union Mount readdir solution

    :::

    While I don't have objection against the implementation in userspace,
    what will UnionMount handle about rmdir or rename dir?
    Those systemcalls need to test whether the dir is *logically* empty or
    not in kernel space, don't they?
    And I am afraid that UnionMount has to implement the similar thing, but
    it never mean to modify glibc is a bad idea.
