摘要:
In the Linux kernel, the following vulnerability has been resolved:dma-buf/sw-sync: don t enable IRQ from sync_print_obj()Since commit a6aa8fca4d79 ( dma-buf/sw-sync: Reduce irqsave/irqrestore fromknown context ) by error replaced spin_unlock_irqrestore() withspin_unlock_irq() for both sync_debugfs_show() and sync_print_obj() despitesync_print_obj() is called from sync_debugfs_show(), lockdep complainsinconsistent lock state warning.Use plain spin_{lock,unlock}() for sync_print_obj(), forsync_debugfs_show() is already using spin_{lock,unlock}_irq().
