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.

DESCRIPTION
EPOLL_CTL_DEL
...
The event argument describes the object linked to the file descriptor
fd. The struct epoll_event is defined as:
typedef union epoll_data {
void *ptr;
int fd;
uint32_t u32;
uint64_t u64;
} epoll_data_t;
struct epoll_event {
uint32_t events; /* Epoll events */
epoll_data_t data; /* User data variable */
};

Summary:
- This commit adds SMP support to cxd56_farapi.c
- nxplayer now works in SMP mode
Impact:
- Spresense in SMP mode only
Testing:
- Add the following configs to spresense:wifi
- +CONFIG_SCHED_INSTRUMENTATION=yy
- +CONFIG_SCHED_INSTRUMENTATION_BUFFER=y
- +CONFIG_SMP=y
- +CONFIG_SMP_NCPUS=2
- +CONFIG_SPINLOCK_IRQ=y
- Run nxplayer and play an WAV file on uSD card
- NOTE: http streaming playback would cause deadlocks

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.
