Snapshots of nilfs are read-only. After super block instances (sb) will be unified, nilfs will need to check write access by a way other than implicit test with IS_RDONLY(inode). This is because IS_RDONLY() refers to MS_RDONLY bit of inode->i_sb->s_flags and it will become inaccurate after the unification of sb. To prepare for the issue, this uses i_op->permission to deny write access to inodes in snapshots. Signed-off-by: NRyusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>

This rewrites functions using ifile so that they get ifile from nilfs_root object, and will remove sbi->s_ifile. Some functions that don't know the root object are extended to receive it from caller. Signed-off-by: NRyusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>

The previous export operations cannot handle multiple versions of a filesystem if they belong to the same sb instance. This adds a new type of file handle and extends export operations so that they can get the inode specified by a checkpoint number as well as an inode number and a generation number.

This puts a pointer to nilfs_root object in the private part of on-memory inode, and makes nilfs_iget function pick up the inode with the same root object. Non-root inodes inherit its nilfs_root object from parent inode. That of the root inode is allocated through nilfs_attach_checkpoint() function.

由 Ryusuke Konishi 提交于
To hold multiple versions of a filesystem in one sb instance, a new on-memory structure is necessary to handle one or more checkpoints. This adds a red-black tree of checkpoints to nilfs object, and adds lookup and create functions for them. Each checkpoint is represented by "nilfs_root" structure, and this structure has rb_node to configure the rb-tree. The nilfs_root object is identified with a checkpoint number. For each snapshot, a nilfs_root object is allocated and the checkpoint number of snapshot is assigned to it. For a regular mount (i.e. current mode mount), NILFS_CPTREE_CURRENT_CNO constant is assigned to the corresponding nilfs_root object. Each nilfs_root object has an ifile inode and some counters. These items will displace those of nilfs_sb_info structure in successive patches. Signed-off-by: NRyusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>

This uses inode hash function that vfs provides instead of the own hash table for caching gc inodes. This finally removes the own inode hash from nilfs. Signed-off-by: NRyusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>

This uses iget5_locked instead of iget_locked so that gc cache can look up inodes with an inode number and an optional checkpoint number. Signed-off-by: NRyusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>
-
由 Ryusuke Konishi 提交于
On-memory inode structures of nilfs have a member "i_cno" which stores a checkpoint number related to the inode. For gc-inodes, this field indicates version of data each gc-inode caches for GC. Log writer temporarily uses "i_cno" to transfer the latest checkpoint number. This stops the latter use and lets only gc-inodes use it. The purpose of this patch is to allow the successive change use "i_cno" for inode lookup. Signed-off-by: NRyusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>

The current nilfs_destroy_inode() doesn't handle metadata file inodes including gc inodes (dummy inodes used for garbage collection). This allows nilfs_destroy_inode() to destroy inodes of metadata files. Signed-off-by: NRyusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>

Compatibility of nilfs partitions is now managed with three feature sets. This changes old compatibility check with revision number so that it can accept future revisions. Note that we can stop support of experimental versions of nilfs that doesn't know the feature sets by incrementing NILFS_CURRENT_REV. We don't have to do it soon, but it would be a possible option whenever the need arises. Signed-off-by: NRyusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>

ATA devices don't send D2H Reg FIS after an successful ATA PIO data-in command. The host is supposed to take the TF and E_Status of the preceding PIO Setup FIS. Update ahci_qc_fill_rtf() such that it takes TF + E_Status from PIO Setup FIS after a successful ATA PIO data-in command. Without this patch, result_tf for such a command is filled with the content of the previous D2H Reg FIS which belongs to a previous command, which can make the command incorrectly seen as failed. * Patch updated to grab the whole TF + E_Status from PIO Setup FIS instead of just E_Status as suggested by Robert Hancock.
