nilfs2: fix incorrect KERN_CRIT messages in case of write failures

2009-07-30T21:39:49Z

commit 4a52df779700080de4afb0436d9dd9188514a69b upstream. In case of write-failure retries, the following KERN_CRIT level messages are mistakenly output by nilfs_dat_commit_start() function: nilfs_dat_commit_start: vbn = 408463, start = 12506, end = 18446744073709551615, pbn = 530210 nilfs_dat_commit_start: vbn = 408515, start = 12506, end = 18446744073709551615, pbn = 530211 nilfs_dat_commit_start: vbn = 408464, start = 12506, end = 18446744073709551615, pbn = 530212 ... This suppresses these messages. Signed-off-by: Ryusuke Konishi Signed-off-by: Greg Kroah-Hartman

nilfs2: replace BUG_ON and BUG calls triggerable from ioctl

2009-04-07T15:31:19Z

Pekka Enberg advised me: > It would be nice if BUG(), BUG_ON(), and panic() calls would be > converted to proper error handling using WARN_ON() calls. The BUG() > call in nilfs_cpfile_delete_checkpoints(), for example, looks to be > triggerable from user-space via the ioctl() system call. This will follow the comment and keep them to a minimum.

nilfs2: disk address translator

2009-04-07T15:31:14Z

This adds the disk address translation file (DAT) whose primary function is to convert virtual disk block numbers to actual disk block numbers. The virtual block numbers of NILFS are associated with checkpoint generation numbers, and this file also provides functions to manage the lifetime information of each virtual block number.
