2007-01-21ocfs2: Directory c/mtime update fixesMark Fasheh1-32/+37
ocfs2 wasn't updating c/mtime on directories during dirent creation/deletion. Fix ocfs2_unlink(), ocfs2_rename() and __ocfs2_add_entry() by adding the proper code to update the struct inode and push the change out to disk. This helps rename/unlink on nfs exported file systems in particular as those clients compare directory time values to avoid a full re-reading a directory which hasn't changed. ocfs2_rename() loses some superfluous error handling as a result of this patch.

2006-12-07ocfs2: local mountsSunil Mushran1-3/+5
This allows users to format an ocfs2 file system with a special flag, OCFS2_FEATURE_INCOMPAT_LOCAL_MOUNT. When the file system sees this flag, it will not use any cluster services, nor will it require a cluster configuration, thus acting like a 'local' file system.

2006-12-01ocfs2: implement i_op->permissionTiger Yang1-0/+1
Implement .permission() in ocfs2_file_iops, ocfs2_special_file_iops and ocfs2_dir_iops. This helps us avoid some multi-node races with mode change and vfs operations. Signed-off-by: Tiger Yang <tiger.yang@oracle.com> Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
2006-12-01ocfs2: Remove struct ocfs2_journal_handle in favor of handle_tMark Fasheh1-19/+19
This is mostly a search and replace as ocfs2_journal_handle is now no more than a container for a handle_t pointer. ocfs2_commit_trans() becomes very straight forward, and we remove some out of date comments / code. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
2006-12-01ocfs2: remove handle argument to ocfs2_start_trans()Mark Fasheh1-5/+5
All callers either pass in NULL directly, or a local variable that is already set to NULL. The internals of ocfs2_start_trans() get a nice cleanup as a result. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
2006-12-01ocfs2: pass ocfs2_super * into ocfs2_commit_trans()Mark Fasheh1-5/+5
This sets us up to remove handle->journal. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
2006-12-01ocfs2: remove unused handle argument from ocfs2_meta_lock_full()Mark Fasheh1-12/+12
Now that this is unused and all callers pass NULL, we can safely remove it. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
2006-12-01ocfs2: Don't allocate handle early in ocfs2_rename()Mark Fasheh1-8/+1
It isn't used until ocfs2_start_trans() anyway. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
2006-12-01ocfs2: don't use handle for locking in allocation functionsMark Fasheh1-20/+6
Instead we record our state on the allocation context structure which all callers already know about and lifetime correctly. This means the reservation functions don't need a handle passed in any more, and we can also take it off the alloc context. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>

2006-10-01[PATCH] r/o bind mounts: clean up OCFS2 nlink handlingMark Fasheh1-20/+19
OCFS2 does some operations on i_nlink, then reverts them if some of its operations fail to complete. This does not fit in well with the drop_nlink() logic where we expect i_nlink to stay at zero once it gets there. So, delay all of the nlink operations until we're sure that the operations have completed. Also, introduce a small helper to check whether an inode has proper "unlinkable" i_nlink counts no matter whether it is a directory or regular inode. This patch is broken out from the others because it does contain some logical changes.

2006-10-01[PATCH] r/o bind mount prepwork: inc_nlink() helperDave Hansen1-4/+4

2006-10-01[PATCH] r/o bind mounts: unlink: monitor i_nlinkDave Hansen1-2/+2
When a filesystem decrements i_nlink to zero, it means that a write must be performed in order to drop the inode from the filesystem. We're shortly going to have keep filesystems from being remounted r/o between the time that this i_nlink decrement and that write occurs. So, add a little helper function to do the decrements. We'll tie into it in a bit to note when i_nlink hits zero.

2006-09-24ocfs2: Remove i_generation from inode lock namesMark Fasheh1-1/+1
OCFS2 puts inode meta data in the "lock value block" provided by the DLM. Typically, i_generation is encoded in the lock name so that a deleted inode on and a new one in the same block don't share the same lvb. Unfortunately, that scheme means that the read in ocfs2_read_locked_inode() is potentially thrown away as soon as the meta data lock is taken - we cannot encode the lock name without first knowing i_generation, which requires a disk read. This patch encodes i_generation in the inode meta data lvb, and removes the value from the inode meta data lock name. This way, the read can be covered by a lock, and at the same time we can distinguish between an up to date and a stale LVB. This will help cold-cache stat(2) performance in particular. Since this patch changes the protocol version, we take the opportunity to do a minor re-organization of two of the LVB fields. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
2006-09-24ocfs2: Remove special casing for inode creation in ocfs2_dentry_attach_lock()Mark Fasheh1-6/+4
We can't use LKM_LOCAL for new dentry locks because an unlink and subsequent re-create of a name/inode pair may result in the lock still being mastered somewhere in the cluster. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
2006-09-24ocfs2: Hook rest of the file system into dentry locking APIMark Fasheh1-34/+82

2006-09-20ocfs2: implement directory read-aheadMark Fasheh1-5/+5
Uptodate.c now knows about read-ahead buffers. Use some more aggressive logic in ocfs2_readdir(). The two functions which currently use directory read-ahead are ocfs2_find_entry() and ocfs2_readdir(). Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
2006-09-20ocfs2: Fix directory link count checks in ocfs2_link()Tiger Yang1-5/+5

2006-09-20ocfs2: move nlink check in ocfs2_mknod()Mark Fasheh1-7/+5
The dir nlink check in ocfs2_mknod() was being done outside of the cluster lock, which means we could have been checking against a stale version of the inode. Fix this by doing the check after the cluster lock instead. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
