looks like a bug

[Fyodor Ustinov <ufm@ufm.su>]

Hi!

root@stb1:~/src# cat a.c
#include <stdio.h>
#include <unistd.h>
#include <fcntl.h>
#include <string.h>
#include <errno.h>


int main(void) {
int fd, rc;
char *s;
struct stat buf;

fd = open("/mnt/aaa",O_RDWR|O_CREAT|O_APPEND,0666);
if (fd == -1) {
printf("Unable to open test file!\n");
exit(0);
}
rc = fstat(fd,&buf);
if (rc != 0) {
s = strerror(errno);
printf("stat rc == %d\nError == '%s'\n",rc,s);
exit(0);
}
rc = write(fd, "kuku", 4);
if (rc == -1) {
s = strerror(errno);
printf("write rc == %d\nError == '%s'\n",rc,s);
}

}

root@stb1:~/src# gcc a.c
a.c: In function ‘main’:
a.c:16:7: warning: incompatible implicit declaration of built-in 
function ‘exit’

root@stb1:~/src# mount -t ceph 10.5.51.230:/ /mnt
root@stb1:~/src# ./a.out

=========

P.S. In cfuse a.out just hang.

WBR,
Fyodor.
