The small tool below triggers this problem for Reuben (confirmed via private mail) but works fine for me on 2.6.13-rc6. johannes --begin test program-- /* Author: Johannes Berg <[email protected]> * * This is a small inotify test program that simply * repeatedly adds and removes watches. */ #include <stdio.h> #include <linux/inotify.h> #include <linux/inotify-syscalls.h> int main() { int fd; int wd1, wd2; int ret; fd = inotify_init(); if (fd < 0) perror("inotify_init"); printf("inotify_init returned fd %d\n", fd); while (1) { wd1 = inotify_add_watch(fd, "/tmp", IN_ALL_EVENTS); if (wd1 < 0) { perror("inotify_add_watch"); break; } printf("inotify_add_watch returned wd1 %d\n", wd1); wd2 = inotify_add_watch(fd, "/", IN_ALL_EVENTS); if (wd2 < 0) { perror("inotify_add_watch"); break; } printf("inotify_add_watch returned wd2 %d\n", wd2); ret = inotify_rm_watch(fd, wd1); if (ret < 0) { perror("inotify_rm_watch wd1"); break; } ret = inotify_rm_watch(fd, wd2); if (ret < 0) { perror("inotify_rm_watch wd2"); break; } } }
