Tejun Heo 01e7ab5b9b kernfs: fix ino wrap-around detection ... commit e23f568aa6 upstream. When the 32bit ino wraps around, kernfs increments the generation number to distinguish reused ino instances. The wrap-around detection tests whether the allocated ino is lower than what the cursor but the cursor is pointing to the next ino to allocate so the condition never triggers. Fix it by remembering the last ino and comparing against that.
