2009-12-03writeback: remove unused nonblocking and congestion checks (gfs2)Wu Fengguang
No one is calling wb_writeback and write_cache_pages with wbc.nonblocking=1 any more. And lumpy pageout will want to do nonblocking writeback without the congestion wait. Signed-off-by: Wu Fengguang <fengguang.wu@intel.com> Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
2009-12-03GFS2: drop rindex glock to refresh rindex listBenjamin Marzinski
When a gfs2 filesystem is grown, it needs to rebuild the rindex list to be able to use the new space. gfs2 does this when the rindex is marked not uptodate, which happens when the rindex glock is dropped. However, on a single node setup, there is never any reason to drop the rindex glock, so gfs2 never invalidates the the rindex. This patch makes gfs2 automatically drop the rindex glock after filesystem grows, so it can refresh the rindex list.

2009-09-16HWPOISON: Enable .remove_error_page for migration aware file systemsAndi Kleen
Enable removing of corrupted pages through truncation for a bunch of file systems: ext*, xfs, gfs2, ocfs2, ntfs These should cover most server needs. I chose the set of migration aware file systems for this for now, assuming they have been especially audited. But in general it should be safe for all file systems on the data area that support read/write and truncate. Caveat: the hardware error handler does not take i_mutex for now before calling the truncate function. Is that ok?

2009-07-30GFS2: keep statfs info in sync on growsBenjamin Marzinski
GFS2 wasn't syncing its statfs info on grows. This causes a problem when you grow the filesystem on multiple nodes. GFS2 would calculate the new space based on the resource groups (which are always current), and then assume that the filesystem had grown the from the existing statfs size. If you grew the filesystem on two different nodes in a short time, the second node wouldn't see the statfs size change from the first node, and would assume that it was grown by a larger amount than it was. When all these changes were synced out, the total fileystem size would be incorrect (the first grow would be counted twice). This patch syncs makes GFS2 read in the statfs changes from disk before a grow, and write them out after the grow, while the master statfs inode is locked.

2009-05-22GFS2: Clean up some file namesSteven Whitehouse
This patch renames the ops_*.c files which have no counterpart without the ops_ prefix in order to shorten the name and make it more readable. In addition, ops_address.h (which was very small) is moved into inode.h and inode.h is cleaned up by adding extern where required. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
