Re: [PATCH 2/2] cifs: limit amount of data we request for xattrs to CIFSMaxBufSize

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

 



Merged into cifs-2.6.git for-next and now testing this with the
buildbot (along the 11 other fixes in for-next, more than half from
Pavel's compounding series, many of them very important and marked for
stable).

Making good progress on cleaning up bugs prior to the (SNIA Europe)
SMB3 test event next week.   The list of xfstests that pass (e.g.
cifs.ko to Samba or Azure or Windows or Macs) continues to increase.
