Zach Brown db62efbbf8 btrfs: don't loop on large offsets in readdir ... When btrfs readdir() hits the last entry it sets the readdir offset to a huge value to stop buggy apps from breaking when the same name is returned by readdir() with concurrent rename()s. But unconditionally setting the offset to INT_MAX causes readdir() to loop returning any entries with offsets past INT_MAX. It only takes a few hours of constant file creation and removal to create entries past INT_MAX. So let's set the huge offset to LLONG_MAX if the last entry has already overflowed 32bit loff_t. Without large offsets behaviour is identical. With large offsets 64bit apps will work and 32bit apps will be no more broken than they currently are if they see large offsets.
