f2fs: add a tracepoint for f2fs_read_data_pages

2015-10-12T21:00:34+00:00

This patch adds a tracepoint for f2fs_read_data_pages to trace when pages are readahead by VFS. Signed-off-by: Chao Yu Signed-off-by: Jaegeuk Kim

f2fs: trace in batches extent info update

2015-10-09T23:20:49+00:00

Rename trace_f2fs_update_extent_tree to trace_f2fs_update_extent_tree_range, then expand and enable it to trace in batches extent info updates. Signed-off-by: Chao Yu Signed-off-by: Jaegeuk Kim

f2fs: check the largest extent at look-up time

2015-08-04T21:09:56+00:00

Because of the extent shrinker or other -ENOMEM scenarios, it cannot guarantee that the largest extent would be cached in the tree all the time. Instead of relying on extent_tree, we can simply check the cached one in extent tree accordingly. Reviewed-by: Chao Yu Signed-off-by: Jaegeuk Kim

f2fs: add f2fs_map_blocks

2015-05-28T22:41:29+00:00

This patch introduces f2fs_map_blocks structure likewise ext4_map_blocks. Now, f2fs uses f2fs_map_blocks when handling get_block. Signed-off-by: Jaegeuk Kim

f2fs: Export the enums in the tracepoints to userspace

2015-04-08T13:40:00+00:00

The tracepoints that use __print_symbolic() use enums as the value to convert to strings. Unfortunately, the format files for these tracepoints show the enum name and not their value. This causes some userspace tools not to know how to convert __print_symbolic() to their strings. Add TRACE_DEFINE_ENUM() macros to export the enums used to userspace to let those tools know what those enum values are.
