-Subject: ext4: check for shutdown and r/o file system in ext4_write_inode()
-
-From: Theodore Ts'o <tytso@mit.edu>
-
-commit 18f2c4fcebf2582f96cbd5f2238f4f354a0e4847 upstream.
-
-If the file system has been shut down or is read-only, then
-ext4_write_inode() needs to bail out early.
-
-Also use jbd2_complete_transaction() instead of ext4_force_commit() so
-we only force a commit if it is needed.
