      ceph: use pagelist to present MDS request data · 25e6bae3
      Yan, Zheng 提交于
      Current code uses page array to present MDS request data. Pages in the
      array are allocated/freed by caller of ceph_mdsc_do_request(). If request
      is interrupted, the pages can be freed while they are still being used by
      the request message.
      
      The fix is use pagelist to present MDS request data. Pagelist is
      reference counted.

      ceph: request xattrs if xattr_version is zero · 508b32d8
      Yan, Zheng 提交于
      Following sequence of events can happen.
        - Client releases an inode, queues cap release message.
        - A 'lookup' reply brings the same inode back, but the reply
          doesn't contain xattrs because MDS didn't receive the cap release
          message and thought client already has up-to-data xattrs.
      
      The fix is force sending a getattr request to MDS if xattrs_version
      is 0. The getattr mask is set to CEPH_STAT_CAP_XATTR, so MDS knows client
      does not have xattr.

      ceph: Fix up after semantic merge conflict · 4db658ea
      Linus Torvalds 提交于
      The previous ceph-client merge resulted in ceph not even building,
      because there was a merge conflict that wasn't visible as an actual data
      conflict: commit 7221fe4c ("ceph: add acl for cephfs") added support
      for POSIX ACL's into Ceph, but unluckily we also had the VFS tree change
      a lot of the POSIX ACL helper functions to be much more helpful to
      filesystems (see for example commits 2aeccbe9 "fs: add generic
      xattr_acl handlers", 5bf3258f "fs: make posix_acl_chmod more useful"
      and 37bc1539 "fs: make posix_acl_create more useful")
      
      The reason this conflict wasn't obvious was many-fold: because it was a
      semantic conflict rather than a data conflict, it wasn't visible in the
      git merge as a conflict.  And because the VFS tree hadn't been in
      linux-next, people hadn't become aware of it that way.  And because I
      was at jury duty this morning, I was using my laptop and as a result not
      doing constant "allmodconfig" builds.
      
      Anyway, this fixes the build and generally removes a fair chunk of the
      Ceph POSIX ACL support code, since the improved helpers seem to match
      really well for Ceph too.  But I don't actually have any way to *test*
      the end result, and I was really hoping for some ACK's for this.  Oh,
      well.
      
      Not compiling certainly doesn't make things easier to test, so I'm
      committing this without the acks after having waited for four hours...
      Plus it's what I would have done for the merge had I noticed the
      semantic conflict..

      I think move the ci->i_ceph_lock down is safe because we can't free
      ceph_inode_info at there.
