Subject: [PATCH v7 0/9] DAX fsync/msync support
Date: Wed, 6 Jan 2016 11:00:54 -0700 [thread overview]
Message-ID: <1452103263-1592-1-git-send-email-ross.zwisler@linux.intel.com> (raw)
Changes since v6 [1]:
1) Fixed an existing NULL pointer dereference bug in __dax_dbg() in patch 1.
2) Fixed an existing bug with the way holes are converted into DAX PMD
entries in patch 2. This solves a BUG_ON reported by Dan Williams.
3) Removed second verification of our radix tree entry before cache flush
in dax_writeback_one(). (Jan Kara)
4) Updated to the new argument list types for dax_pmd_dbg(). (Dan Williams)
5) Fixed the text of a random debug message so that it accurately reflects
the error being found.
This series replaces v6 in the MM tree and in the "akpm" branch of the next
tree. A working tree can be found here:
