[PATCH v5 0/2] vfs: have syncfs() return error when there are writeback errors

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

 



v5:
- use RCU to ensure that bd_super doesn't go away while we're using it

This is the fifth iteration of this patchset. The main difference from
v4 is that this one uses RCU to ensure validity of the bd_super pointer
when we're marking it after a buffer_head writeback error.

Jeff Layton (2):
  vfs: track per-sb writeback errors and report them to syncfs
  buffer: record blockdev write errors in super_block that it backs
