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: pass checkpoint reason on roll-forward recovery

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.

f2fs: split UMOUNT and FASTBOOT flags

2015-02-12T01:04:41+00:00

This patch adds FASTBOOT flag into checkpoint as follows. - CP_UMOUNT_FLAG is set when system is umounted. - CP_FASTBOOT_FLAG is set when intermediate checkpoint having node summaries was done. So, if you get CP_UMOUNT_FLAG from checkpoint, the system was umounted cleanly. Instead, if there was sudden-power-off, you can get CP_FASTBOOT_FLAG or nothing.

f2fs: merge flags in struct f2fs_sb_info

2015-02-12T01:04:38+00:00

Currently, there are several variables with Boolean type as below: struct f2fs_sb_info { ... int s_dirty; bool need_fsck; bool s_closing; ... bool por_doing; ... } For this there are some issues: 1. there are some space of f2fs_sb_info is wasted due to aligning after Boolean type variables by compiler. 2. if we continuously add new flag into f2fs_sb_info, structure will be messed up. So in this patch, we try to: 1. switch s_dirty to Boolean type variable since it has two status 0/1. 2. merge s_dirty/need_fsck/s_closing/por_doing variables into s_flag. 3. introduce an enum type which can indicate different states of sbi. 4. use new introduced universal interfaces is_sbi_flag_set/{set,clear}_sbi_flag to operate flags for sbi. After that, above issues will be fixed. Signed-off-by: Chao Yu Signed-off-by: Jaegeuk Kim
