## Description

In the Linux kernel, the following vulnerability has been resolved:  ext4: guard against EA inode refcount underflow in xattr update  syzkaller found a path where ext4_xattr_inode_update_ref() reads an EA inode refcount that is already <= 0 and then applies ref_change (often -1). That lets the refcount underflow and we proceed with a bogus value, triggering errors like:    EXT4-fs error: EA inode <n> ref underflow: ref_count=-1 ref_change=-1   EXT4-fs warning: ea_inode dec ref err=-117  Make the invariant explicit: if the current refcount is non-positive, treat this as on-disk corruption, emit ext4_error_inode(), and fail the operation with -EFSCORRUPTED instead of updating the refcount. Delete the WARN_ONCE() as negative refcounts are now impossible; keep error reporting in ext4_error_inode().  This prevents the underflow and the follow-on orphan/cleanup churn.
