There's also an error flag on the address_space. > Are there any guidelines as far as which should be used? Ideally both. The Page error flag prevents the data from being consumed and the address space error flag makes sure errors are getting reported on fsync()/close() etc. Also AS error is useful when you don't have a clear page to assign the error to, e.g. if you get an error indication that's not tied to a read operation. BTW the upcoming hwpoison code can set such errors asynchronously under you. -Andi -- ak@xxxxxxxxxxxxxxx -- Speaking for myself only. -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
