#     Merge tag 'trace-v6.8-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace
#     
#     Pull tracing and eventfs fixes from Steven Rostedt:
#     
#      - Fix the return code for ring_buffer_poll_wait()
#     
#        It was returing a -EINVAL instead of EPOLLERR.
#     
#      - Zero out the tracefs_inode so that all fields are initialized.
#     
#        The ti->private could have had stale data, but instead of just
#        initializing it to NULL, clear out the entire structure when it is
#        allocated.
#     
#      - Fix a crash in timerlat
#     
#        The hrtimer was initialized at read and not open, but is canceled at
#        close. If the file was opened and never read the close will pass a
#        NULL pointer to hrtime_cancel().
#     
#      - Rewrite of eventfs.
#     
#        Linus wrote a patch series to remove the dentry references in the
#        eventfs_inode and to use ref counting and more of proper VFS
#        interfaces to make it work.
#     
#      - Add warning to put_ei() if ei is not set to free. That means
#        something is about to free it when it shouldn't.
#     
#      - Restructure the eventfs_inode to make it more compact, and remove the
#        unused llist field.
#     
#      - Remove the fsnotify*() funtions for when the inodes were being
#        created in the lookup code. It doesn't make sense to notify about
#        creation just because something is being looked up.
#     
#      - The inode hard link count was not accurate.
#     
#        It was being updated when a file was looked up. The inodes of
#        directories were updating their parent inode hard link count every
#        time the inode was created. That means if memory reclaim cleaned a
#        stale directory inode and the inode was lookup up again, it would
#        increment the parent inode again as well. Al Viro said to just have
#        all eventfs directories have a hard link count of 1. That tells user
#        space not to trust it.
#
