...ns with an error if found (the extent_range_uptodate() function returns 1 on errors). After testing this patch, the user reported that the error with the NULL pointer oops was solved. However, there is still a remaining problem with a thread becoming stuck in wait_on_page_locked(page) in the read_extent_buffer_pages(...) function in extent_io.c for (i = start_i; i < num_pages; i++) { page = extent_buffer_page(eb, i); wait_on_page_locked(page); if (!PageUptodate(page)) ret = -EIO; } This patch leaves the issue with the lock...

Hi gang, Here''s some trivial cleanups that I''ve built up while reading through the code. They''ve been run through xfstests -g quick. - z -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

Hi all - The following 9 patches add more error handling to the btrfs code: - Add btrfs_panic - Catch locking failures in {set,clear}_extent_bit - Push up set_extent_bit errors to callers - Push up lock_extent errors to callers - Push up clear_extent_bit errors to callers - Push up unlock_extent errors to callers - Make pin_down_extent return void - Push up btrfs_pin_extent errors to

...to extent_buffer flags. - Fix a race when triggering the read. - Fix a bug where only parts of the requested range where actually prefetched. The hit only when requesting parts of a tree, so the above numbers doesn''t change. Arne Jansen (6): btrfs: add an extra wait mode to read_extent_buffer_pages btrfs: add READAHEAD extent buffer flag btrfs: state information for readahead btrfs: initial readahead code and prototypes btrfs: hooks for readahead btrfs: test ioctl for readahead fs/btrfs/Makefile | 3 +- fs/btrfs/ctree.h | 13 + fs/btrfs/disk-io.c | 84 ++++- fs/b...

Hi all - Here''s my current error handling patchset, against 3.1-rc8. Almost all of this patchset is preparing for actual error handling. Before we start in on that work, I''m trying to reduce the surface we need to worry about. It turns out that there is a ton of code that returns an error code but never actually reports an error. The patchset has grown to 65 patches. 46 of them

...it only when requesting parts of a tree, so the above numbers doesn''t change. Change from v2: - use rcu instead of transaction to protect root->node Change from v3: - rebased to current for-linus - in v3 patch 1 was missing Arne Jansen (7): btrfs: add an extra wait mode to read_extent_buffer_pages btrfs: add READAHEAD extent buffer flag btrfs: state information for readahead btrfs: initial readahead code and prototypes btrfs: hooks for readahead btrfs: test ioctl for readahead btrfs: use readahead API for scrub fs/btrfs/Makefile | 3 +- fs/btrfs/ctree.h | 13 + fs...
