- * For inode 0, i.e. $MFT itself, we cannot use ilookup5() from here or
- * we deadlock because the inode is already locked by the kernel
- * (fs/fs-writeback.c::__sync_single_inode()) and ilookup5() waits
- * until the inode is unlocked before returning it and it never gets
- * unlocked because ntfs_should_write_mft_record() never returns. )-:
- * Fortunately, we have inode 0 pinned in icache for the duration of
- * the mount so we can access it directly.
+ * Optimize inode 0, i.e. $MFT itself, since we have it in memory and
+ * we get here for it rather often.
