[PATCH v2 4/9] nilfs2: set the mapping error when calling SetPageError on writeback

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



In a later patch, we're going to want to make the fsync codepath not do
a TestClearPageError call as that can override the error set in the
address space. To do that though, we need to ensure that filesystems
that are relying on the PG_error bit for reporting writeback errors
also set an error in the address space.

Ensure that this is set in nilfs2.
