    Subject[PATCH 00/34] vfs: atomic open v3
    Date
    This series allows clean implementation of atomic lookup+(create)+open
    operations that previously were done via ->lookup and ->create using open
    intents.

    Changes from the last version:

    - fixed some bugs
    - pulled the EOPENSTALE patches towards the head of the queue
    - split up some patches for easier reviewability

    git tree is here:

    git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/vfs.git atomic-open.v3

    Thanks,
    Miklos

    vfs: make follow_link check RCU safe
    vfs: do_last(): make ENOENT exit RCU safe

    vfs: do_last(): add audit_inode before open
    vfs: do_last() common post lookup
    vfs: split __dentry_open()
    vfs: do_dentry_open(): don't put filp
