      gfs2: buffered write prefaulting · fa5dfa64
      Andreas Gruenbacher authored
      In gfs2_file_buffered_write, to increase the likelihood that all the
      user memory we're trying to write will be resident in memory, carry out
      the write in chunks and fault in each chunk of user memory before trying
      to write it.  Otherwise, some workloads will trigger frequent short
      "internal" writes, causing filesystem blocks to be allocated and then
      partially deallocated again when writing into holes, which is wasteful
      and breaks reservations.
      
      Neither the chunked writes nor any of the short "internal" writes are
      user visible.

      gfs2: Align read and write chunks to the page cache · 324d116c
      Andreas Gruenbacher authored
      Align the chunks that reads and writes are carried out in to the page
      cache rather than the user buffers.  This will be more efficient in
      general, especially for allocating writes.  Optimizing the case that the
      user buffer is gfs2 backed isn't very useful; we only need to make sure
      we won't deadlock.

      gfs2: Pull return value test out of should_fault_in_pages · 72382264
      Andreas Gruenbacher authored
      Pull the return value test of the previous read or write operation out
      of should_fault_in_pages().  In a following patch, we'll fault in pages
      before the I/O and there will be no return value to check.

      gfs2: Variable rename · 42e4c3bd
      Andreas Gruenbacher authored
      Instead of counting the number of bytes read from the filesystem,
      functions gfs2_file_direct_read and gfs2_file_read_iter count the number
      of bytes written into the user buffer.  Conversely, functions
      gfs2_file_direct_write and gfs2_file_buffered_write count the number of
      bytes read from the user buffer.  This is nothing but confusing, so
      change the read functions to count how many bytes they have read, and
      the write functions to count how many bytes they have written.

      gfs2: Fix filesystem block deallocation for short writes · d031a886
      Andreas Gruenbacher authored
      When a write cannot be carried out in full, gfs2_iomap_end() releases
      blocks that have been allocated for this write but haven't been used.
      
      To compute the end of the allocation, gfs2_iomap_end() incorrectly
      rounded the end of the attempted write down to the next block boundary
      to arrive at the end of the allocation.  It would have to round up, but
      the end of the allocation is also available as iomap->offset +
      iomap->length, so just use that instead.
      
      In addition, use round_up() for computing the start of the unused range.
