      Btrfs: fix pages truncation in btrfs_ioctl_clone() · 71ef0786
      Li Zefan 提交于
      It's a bug in commit f81c9cdc
      (Btrfs: truncate pages from clone ioctl target range)
      
      We should pass the dest range to the truncate function, but not the
      src range.
      
      Also move the function before locking extent state.

      btrfs: fix d_off in the first dirent · 3765fefa
      Hidetoshi Seto 提交于
      Since the d_off in the first dirent for "." (that originates from
      the 4th argument "offset" of filldir() for the 2nd dirent for "..")
      is wrongly assigned in btrfs_real_readdir(), telldir returns same
      offset for different locations.
      
       | # mkfs.btrfs /dev/sdb1
       | # mount /dev/sdb1 fs0
       | # cd fs0
       | # touch file0 file1
       | # ../test
       | telldir: 0
       | readdir: d_off = 2, d_name = "."
       | telldir: 2
       | readdir: d_off = 2, d_name = ".."
       | telldir: 2
       | readdir: d_off = 3, d_name = "file0"
       | telldir: 3
       | readdir: d_off = 2147483647, d_name = "file1"
       | telldir: 2147483647
      
      To fix this problem, pass filp->f_pos (which is loff_t) instead.
      
       | # ../test
       | telldir: 0
       | readdir: d_off = 1, d_name = "."
       | telldir: 1
       | readdir: d_off = 2, d_name = ".."
       | telldir: 2
       | readdir: d_off = 3, d_name = "file0"
       :
      
      At the moment the "offset" for "." is unused because there is no
      preceding dirent, however it is better to pass filp->f_pos to follow
      grammatical usage.
