| | | | | | | | | | | | | | | | | | | | | | files at once on a filesystem running soft updates. The root of the problem is that soft updates limits the amount of memory that may be allocated to dependency structures so as to avoid hogging kernel memory. The original algorithm just waited for the disk I/O to catch up and reduce the number of dependencies. This new code takes a much more aggressive approach. Basically there are two resources that routinely hit the limit. Inode dependencies during periods with a high file creation rate and file and block removal dependencies during periods with a high file removal rate. I have attacked these problems from two fronts. When the inode dependency limits are reached, I pick a random inode dependency, UFS_UPDATE it together with all the other dirty inodes contained within its disk block and then write that disk block. This trick usually clears 5-50 inode dependencies in a single disk I/O. For block and file removal dependencies, I pick a random directory page that has at least one remove pending and VOP_FSYNC its directory. That releases all its removal dependencies to the work queue. To further hasten things along, I also immediately start the work queue process rather than waiting for its next one second scheduled run.

* Fix 'noatime' bug that was unrelated to use of noatime.nate1998-10-031-1/+10
| | | | | | | | | | | | | | | | | | | | | | | The problem is caused when a directory block is compacted. When this occurs, softdep_change_directoryentry_offset() is called to relocate each directory entry and adjust its matching diradd structure, if any, to match the new location of the entry. The bug is that while softdep_change_directoryentry_offset() correctly adjusts the offsets of the diradd structures on the pd_diraddhd[] lists (which are not yet ready to be committed to disk), it fails to adjust the offsets of the diradd structures on the pd_pendinghd list (which are ready to be committed to disk). This causes the dependency structures to be inconsistent with the buf contents. Now, if the compaction has moved a directory entry to the same offset as one of the diradd structures on the pd_pendinghd list *and* a syscall is done that tries to remove this directory entry before this directory block has been written to disk (which would empty pd_pendinghd), a sanity check in newdirrem() will call panic() when it notices that the inode number in the entry that it is to be removed doesn't match the inode number in the diradd structure with that offset of that entry.

I don't know how kirk could have missed such a glaring problem for so long. :-) Especially since the inconsitency survived on the disk for a whole 4 second on average before being fixed by other code.
