Hi!
I'm trying to use debugfs_create_u32_array() in drivers/net/netdevsim and it causes memory leaks:
unreferenced object 0xffff8880546642a0 (size 16): comm "test_udp_tuns.s", pid 2146, jiffies 4294928368 (age 3772.435s) hex dump (first 16 bytes): 84 52 6a 4d 80 88 ff ff 04 00 00 00 f3 78 7e 89 .RjM.........x~. backtrace: [<000000006962a447>] debugfs_create_u32_array+0x3f/0x90
I can see that debugfs_create_u32_array() allocates a structure at create time that ends up assigned to inode->i_private, but I don't see it freed anywhere.
Am I missing something? I'm pretty sure files get removed, cause the driver calls debugfs_remove_recursive() and no other file types leaks.
