2006-01-14[PATCH] Add tmpfs options for memory placement policiesRobin Holt1-1/+1
Anything that writes into a tmpfs filesystem is liable to disproportionately decrease the available memory on a particular node. Since there's no telling what sort of application (e.g. dd/cp/cat) might be dropping large files there, this lets the admin choose the appropriate default behavior for their site's situation. Introduce a tmpfs mount option which allows specifying a memory policy and a second option to specify the nodelist for that policy. With the default policy, tmpfs will behave as it does today. This patch adds support for preferred, bind, and interleave policies. The default policy will cause pages to be added to tmpfs files on the node which is doing the writing. Some jobs expect a single process to create and manage the tmpfs files. This results in a node which has a significantly reduced number of free pages. With this patch, the administrator can specify the policy and nodes for that policy where they would prefer allocations. This patch was originally written by Brent Casavant and Hugh Dickins. I added support for the bind and preferred policies and the mpol_nodelist mount option.

2006-01-13[PATCH] Fix oops in ufs_fill_super at mount timeEvgeniy1-2/+2
There's a lack of parenthesis in fs/ufs/utils.h, so instead of the 512th byte of buffer, the usb2 pointer will point to the nth structure of type ufs_super_block_second.

2006-01-11[PATCH] reiserfs: fix assertion failure in reiserfs+journaled quotasJan Kara1-1/+4
Sometimes we call do_journal_end() with t_refcount == 0. If quota is turned on and we happen to have some inode with preallocation bad things happen as we try to use the current handle for quota operations. Checks for t_refcount in journal_begin() fail and we Oops. We raise t_refcount to make those checks happy. We should not cause any bad as all the needed quota blocks should be already attached to the transaction (they were attached to the transaction when we allocated those preallocation blocks).

extracting the work from its queue. In addition, this processing also decrement the inode's i_count.

2006-01-11[XFS] Initial pass at going directly-to-bio on the buffered IO path. ThisChristoph Hellwig4-364/+431
allows us to submit much larger I/Os instead of sending down lots of small buffer_heads. To do this we need to have a rather complicated I/O submission and completion tracking infrastructure. Part of the latter has been merged already a long time ago for direct I/O support. Part of the problem is that we need to track sub-pagesize regions and for that we still need buffer_heads for the time beeing. Long-term I hope we can move to better data strucutures and/or maybe move this to fs/mpage.c instead of having it in XFS.
