Title
f2fs: quota: fix loop condition at f2fs_quota_sync()
Summary
In the Linux kernel, the following vulnerability has been resolved:
f2fs: quota: fix loop condition at f2fs_quota_sync()
cnt should be passed to sb_has_quota_active() instead of type to check
active quota properly.
Moreover, when the type is -1, the compiler with enough inline knowledge
can discard sb_has_quota_active() check altogether, causing a NULL pointer
dereference at the following inode_lock(dqopt->files[cnt]):
