It creates one watch for file "0" to demonstrate the problem. Afterwards it creates and removes watches again and again just to force idr_alloc_cyclic to reach INT_MAX. Then events are created for file "0" on the queue. The watch for "0" is removed. A watch for another file is created. Example program output (after a few hours, on Linux 3.14.4 x86_64): ... 2147459044 2147467235 2147475426 2147483617 2147483647 Preparation done BINGO Collision detected Watch descriptor 1 for /tmp/test/8192 Watch descriptor 1 for /tmp/test/0 -- You are receiving this mail because: You are watching the assignee of the bug. -- To unsubscribe from this list: send the line "unsubscribe linux-man" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
