Subject: [PATCH v2 0/2] zonefs: Fix data corruption and error return
Date: Thu, 30 Mar 2023 10:54:21 +0900	[thread overview]
Message-ID: <20230330015423.2170293-1-damien.lemoal@opensource.wdc.com> (raw)

Patch 1 fixes a potential data corruption when the last page of the
inode is cached and a sync append direct write partially modify the
data of that page on disk. The second patch avoids propagating to user
space the -ENOTBLK error potentially returned by iomap_dio_rw().

Changes from v1:
 - Reworked patch 1 commit message and use an exact end argument for the
   call to invalidate_inode_pages2_range().
 - Added patch 2.

Damien Le Moal (2):
  zonefs: Always invalidate last cached page on append write
  zonefs: Do not propagate iomap_dio_rw() ENOTBLK error to user space
