Hi!
Just discovered this BUG_ON() result in logs. Happened while a system was under a very disk/memory-intensive load.
This is unlikely to be a memory corruption (pretty new ThinkPad with original memory).
BUG_ON called from here:
static void sysfs_d_iput(struct dentry * dentry, struct inode * inode) { struct sysfs_dirent * sd = dentry->d_fsdata;
if (sd) { BUG_ON(sd->s_dentry != dentry); sd->s_dentry = NULL; sysfs_put(sd); } iput(inode); }
Bug report below. Please CC me
Yury.
