      splice: check f_mode for seekable file · 19c9a49b
      由 Changli Gao 提交于 
      check f_mode for seekable file

As a seekable file is allowed without a llseek function, so the old way isn't
work any more.

      splice: direct_splice_actor() should not use pos in sd · 2cb4b05e
      由 Changli Gao 提交于 
      direct_splice_actor() shouldn't use sd->pos, as sd->pos is for file reading,
file->f_pos should be used instead.

      fs: fix superblock iteration race · 57439f87
      由 npiggin@suse.de 提交于 
      list_for_each_entry_safe is not suitable to protect against concurrent
modification of the list. 6754af64 introduced a race in sb walking.

list_for_each_entry can use the trick of pinning the current entry in
the list before we drop and retake the lock because it subsequently
follows cur->next. However list_for_each_entry_safe saves n=cur->next
for following before entering the loop body, so when the lock is
dropped, n may be deleted.
