Return EEXISTS if requested file already exists, without this patch open call will always succeed even if the file exists and user specified O_CREAT|O_EXCL. Following test code can be used to verify this patch. Without this patch executing following test code on 9p mount will result in printing 'test case failed' always. main() { int fd; /* first create the file */ fd = open("./file", O_CREAT|O_WRONLY); if (fd < 0) { perror("open"); return -1; } close(fd); /* Now opening same file with O_CREAT|O_EXCL should fail */ fd = open("./file", O_CREAT|O_EXCL); if (fd < 0 && errno == EEXIST) printf("test case pass\n"); else printf("test case failed\n"); close(fd); return 0; } Signed-off-by: NM.

This make sure we don't use wrong inode from the inode hash. The inode number of the file deleted is reused by the next file system object created and if we only use inode number for inode hash lookup we could end up with wrong struct inode. Also compare inode generation number. Not all Linux file system provide st_gen in userspace.
