      cifs: clean up various nits in unicode routines (try #2) · 581ade4d
      Jeff Layton 提交于
      Minor revision to the original patch. Don't abuse the __le16 variable
      on the stack by casting it to wchar_t and handing it off to char2uni.
      Declare an actual wchar_t on the stack instead. This fixes a valid
      sparse warning.
      
      Fix the spelling of UNI_ASTERISK. Eliminate the unneeded len_remaining
      variable in cifsConvertToUCS.
      
      Also, as David Howells points out. We were better off making
      cifsConvertToUCS *not* use put_unaligned_le16 since it means that we
      can't optimize the mapped characters at compile time. Switch them
      instead to use cpu_to_le16, and simply use put_unaligned to set them
      in the string.

      cifs: clean up length checks in check2ndT2 · c0c7b905
      Jeff Layton 提交于
      Thus spake David Howells:
      
      The code that follows this:
      
        	remaining = total_data_size - data_in_this_rsp;
      	if (remaining == 0)
      		return 0;
      	else if (remaining < 0) {
      
      generates better code if you drop the 'remaining' variable and compare
      the values directly.
      
      Clean it up per his recommendation...

      cifs: set ra_pages in backing_dev_info · 2b6c26a0
      Jeff Layton 提交于
      Commit 522440ed made cifs set backing_dev_info on the mapping attached
      to new inodes. This change caused a fairly significant read performance
      regression, as cifs started doing page-sized reads exclusively.
      
      By virtue of the fact that they're allocated as part of cifs_sb_info by
      kzalloc, the ra_pages on cifs BDIs get set to 0, which prevents any
      readahead. This forces the normal read codepaths to use readpage instead
      of readpages causing a four-fold increase in the number of read calls
      with the default rsize.
      
      Fix it by setting ra_pages in the BDI to the same value as that in the
      default_backing_dev_info.
      
      Fixes https://bugzilla.kernel.org/show_bug.cgi?id=31662

      cifs: always do is_path_accessible check in cifs_mount · 70945643
      Jeff Layton 提交于
      Currently, we skip doing the is_path_accessible check in cifs_mount if
      there is no prefixpath. I have a report of at least one server however
      that allows a TREE_CONNECT to a share that has a DFS referral at its
      root. The reporter in this case was using a UNC that had no prefixpath,
      so the is_path_accessible check was not triggered and the box later hit
      a BUG() because we were chasing a DFS referral on the root dentry for
      the mount.
      
      This patch fixes this by removing the check for a zero-length
      prefixpath.  That should make the is_path_accessible check be done in
      this situation and should allow the client to chase the DFS referral at
      mount time instead.

      cifs: replace /proc/fs/cifs/Experimental with a module parm · bdf1b03e
      Jeff Layton 提交于
      This flag currently only affects whether we allow "zero-copy" writes
      with signing enabled. Typically we map pages in the pagecache directly
      into the write request. If signing is enabled however and the contents
      of the page change after the signature is calculated but before the
      write is sent then the signature will be wrong. Servers typically
      respond to this by closing down the socket.
      
      Still, this can provide a performance benefit so the "Experimental" flag
      was overloaded to allow this. That's really not a good place for this
      option however since it's not clear what that flag does.
      
      Move that flag instead to a new module parameter that better describes
      its purpose. That's also better since it can be set at module insertion
      time by configuring modprobe.d.

      'min_align'.
      
      Since then, another use of that 'align' variable got introduced by

      ext4: sync the directory inode in ext4_sync_parent() · 0893ed45
      Curt Wohlgemuth 提交于
      ext4 has taken the stance that, in the absence of a journal,
      when an fsync/fdatasync of an inode is done, the parent
      directory should be sync'ed if this inode entry is new.
      ext4_sync_parent(), which implements this, does indeed sync
      the dirent pages for parent directories, but it does not
      sync the directory *inode*.  This patch fixes this.
      
      Also now return error status from ext4_sync_parent().
      
      I tested this using a power fail test, which panics a
      machine running a file server getting requests from a
      client.  Without this patch, on about every other test run,
      the server is missing many, many files that had been synced.
      With this patch, on > 6 runs, I see zero files being lost.

      nfsd4: fix oops on lock failure · 23fcf2ec
      J. Bruce Fields 提交于
      Lock stateid's can have access_bmap 0 if they were only partially
      initialized (due to a failed lock request); handle that case in
      free_generic_stateid.
