Description:
In the Linux kernel, the following vulnerability has been resolved: jfs: Fix shift-out-of-bounds in dbDiscardAG When searching for the next smaller log2 block, BLKSTOL2() returned 0, causing shift exponent -1 to be negative. This patch fixes the issue by exiting the loop directly when negative shift is found.
