| anonymous enum |
| int nilfs_attach_log_writer | ( | struct super_block * | sb, |
| struct nilfs_root * | root | ||
| ) |
nilfs_attach_log_writer - attach log writer : super block instance : root object of the current filesystem tree
This allocates a log writer object, initializes it, and starts the log writer.
Return Value: On success, 0 is returned. On error, one of the following negative error code is returned.
%-ENOMEM - Insufficient memory available.
| int nilfs_clean_segments | ( | struct super_block * | , |
| struct nilfs_argv * | , | ||

| int nilfs_construct_dsync_segment | ( | struct super_block * | sb, |
| struct inode * | inode, | ||
| loff_t | start, | ||
| loff_t | end | ||
| ) |
nilfs_construct_dsync_segment - construct a data-only logical segment : super block : inode whose data blocks should be written out : start byte offset : end byte offset (inclusive)
Return Value: On success, 0 is retured. On errors, one of the following negative error code is returned.
%-EROFS - Read only filesystem.
%-EIO - I/O error
%-ENOSPC - No space left on device (only in a panic state).
%-ERESTARTSYS - Interrupted.
%-ENOMEM - Insufficient memory available.
| int nilfs_construct_segment | ( | struct super_block * | sb | ) |
nilfs_construct_segment - construct a logical segment : super block
Return Value: On success, 0 is retured. On errors, one of the following negative error code is returned.
%-EROFS - Read only filesystem.
%-EIO - I/O error
%-ENOSPC - No space left on device (only in a panic state).
%-ERESTARTSYS - Interrupted.
%-ENOMEM - Insufficient memory available.

| int nilfs_salvage_orphan_logs | ( | struct the_nilfs * | nilfs, |
| struct super_block * | sb, | ||
| struct nilfs_recovery_info * | ri | ||
| ) |
nilfs_salvage_orphan_logs - salvage logs written after the latest checkpoint : nilfs object : super block instance : pointer to a nilfs_recovery_info struct to store search results.
Return Value: On success, 0 is returned. On error, one of the following negative error code is returned.
%-EINVAL - Inconsistent filesystem state.
%-EIO - I/O error
%-ENOSPC - No space left on device (only in a panic state).
%-ERESTARTSYS - Interrupted.
%-ENOMEM - Insufficient memory available.

| int nilfs_search_super_root | ( | struct the_nilfs * | nilfs, |
| struct nilfs_recovery_info * | ri | ||
| ) |
nilfs_search_super_root - search the latest valid super root : the_nilfs : pointer to a nilfs_recovery_info struct to store search results.
nilfs_search_super_root() looks for the latest super-root from a partial segment pointed by the superblock. It sets up struct the_nilfs through this search. It fills nilfs_recovery_info (ri) required for recovery.
Return Value: On success, 0 is returned. On error, one of the following negative error code is returned.
%-EINVAL - No valid segment found
%-EIO - I/O error
%-ENOMEM - Insufficient memory available.
