9393572aea Revert "fs/nxffs: Fix scan good block slowly and scan an invalid block"
This reverts commit 97be116a39.

This commit broke nxffs.  This leaves the first block as empty which
then exposes another bug where when the pack is called because we
have reached the end of flash and need to look for deleted inodes
we search the first block find no inode and assume that there
are no more inodes.  This then results in corrupting the filesystem
by writing over existing inodes.

This can be seen by runing the sim:nxffs configuration.
Prior to this commit the first pass of writing files would look like
this:

6aee468d72 eventfd: remove the unique minor limit
The unique minor limit of 255 will overflow easily in
some scenarios where eventfd needs to be create/destroy
frequently:

  while (1)
    {
      fd = eventfd(0, 0);  // minor++
      sleep(1);
      close(fd);
    }

remove the unique minor limit.

d452a05910 pollnotify: we should send poll events before semaphore incrementes.
There is a good case on sim platform:
When we input some cmd and click enter key to start application in terminal,
this context will change to application from IDLE loop. Althrough entey key '\r'
has been received to recv buffer and complete post semaphore of reader, but
pollnotify may not be called because context change. So when application run
poll function, because no events happend and poll enter wait, context will
again change to IDLE loop, this pollnotify of IDLE loop will run to send poll
events, poll function of applicaton will wake up. It's wrong!

a354b9a9d1 fs/vfs: Implement EPOLLONESHOT flag
https://linux.die.net/man/2/epoll_ctl:
EPOLLONESHOT (since Linux 2.6.2)
Sets the one-shot behavior for the associated file descriptor.
This means that after an event is pulled out with epoll_wait(2)
the associated file descriptor is internally disabled and
no other events will be reported by the epoll interface.
The user must call epoll_ctl() with EPOLL_CTL_MOD to
rearm the file descriptor with a new event mask.

e880bc9a71 Remove unused, non-modular procfs reference
fs/procfs/fs_procfs.c contained an unused reference to an STM32 procfs structure.  This is wrong in two ways:  (1) There should be not STM32 references outside of arch/arm and boards/arm and (2) the declare STM32 structure is not used anyway.

b89737395b vfs/epoll: add epoll_create1(2) implement
Linux Programmer's Manual

NAME
       epoll_create, epoll_create1 - open an epoll file descriptor

...
SYNOPSIS
       #include <sys/epoll.h>

       int epoll_create1(int flags);
...

   epoll_create1()
       If flags is 0, then, other than the fact that the obsolete
       size argument is dropped, epoll_create1() is the same as
       epoll_create(). The following value can be included in flags
       to obtain different behavior:

       EPOLL_CLOEXEC
              Set the close-on-exec (FD_CLOEXEC) flag on the new file
              descriptor. See the description of the O_CLOEXEC flag in
              open(2) for reasons why this may be useful.

b256b2055f Add support to hard links to CROMFS
This will resolve numerous problems with the way that hard links, in particular "." and ".." are handled.  Instead of trying to fudge the stat flags, the correct implementation is to follow the hard link to the final link target node.  That is what must determine the attributes of the directory entry.

32e98790c0 Correct ROMFS hardlink handling
This PR corrects an error in the ROMFS file system.  The error occurred after following a hard link (depending on how the ROMFS image is organized).  The error occurred because some of the information buffered before following the links was stale and, hence, out of sync after following the hard link.  This would cause random errors when paths containing hardlinks were used with ROMFS.

This PR resolves Issue #1543.  Please compare the following output with the output in Issue #1543 to see how the problem was resolved:
