Subject: a question for i_inode's i_size in ext2
Date: Fri, 26 Sep 2008 13:53:24 +0900	[thread overview]
Message-ID: <2014bcab0809252153v65ebd234le5de8ae27181ae1e@mail.gmail.com> (raw)

  Thank you for the answering.

  In ext2, it seems to me that inode's i_size field can be accessed
without holding i_mutex
  nor thorugh i_size_read function.

  For example, in ext2_update_inode() can be invoked without holding i_mutex.
  However, it freely access i_size field.

  Are these accesses can race with each others?


  Sincerely
  Shin Hong
