      f2fs: fix to return exact trimmed size · f56aa1c5
      Jaegeuk Kim authored
      
      
      Now, we add all the candidates for trim commands and then finally issue
      discard commands.
      So, we should count the trimmed size in back-end.

      f2fs: support FALLOC_FL_INSERT_RANGE · f62185d0
      Chao Yu authored
      FALLOC_FL_INSERT_RANGE flag for ->fallocate was introduced in commit
      dd46c787
      
       ("fs: Add support FALLOC_FL_INSERT_RANGE for fallocate").
      
      The effect of FALLOC_FL_INSERT_RANGE command is the opposite of
      FALLOC_FL_COLLAPSE_RANGE, if this command was performed, all data from
      offset to EOF in our file will be shifted to right as given length, and
      then range [offset, offset + length] becomes a hole.
      
      This command is useful for our user who wants to add some data in the
      middle of the file, for example: video/music editor will insert a keyframe
      in specified position of media file, with this command we can easily create
      a hole for inserting without removing original data.
      
      This patch introduces f2fs_insert_range() to support FALLOC_FL_INSERT_RANGE.
