I test power-failure case by changing src/godown to use new macro, until now, I didn't catch any consistent problem. :) Reviewed-by: Chao Yu <chao2.yu@samsung.com> Thanks, > --- > fs/f2fs/f2fs.h | 1 + > fs/f2fs/file.c | 4 ++++ > 2 files changed, 5 insertions(+) > > diff --git a/fs/f2fs/f2fs.h b/fs/f2fs/f2fs.h > index aad4720..f05ae22 100644 > --- a/fs/f2fs/f2fs.h > +++ b/fs/f2fs/f2fs.h > @@ -250,6 +250,7 @@ static inline bool __has_cursum_space(struct f2fs_summary_block *sum, int > size, > #define F2FS_GOING_DOWN_FULLSYNC 0x0 /* going down with full sync */ > #define F2FS_GOING_DOWN_METASYNC 0x1 /* going down with metadata */ > #define F2FS_GOING_DOWN_NOSYNC 0x2 /* going down */ > +#define F2FS_GOING_DOWN_METAFLUSH 0x3 /* going down with meta flush */ > > #if defined(__KERNEL__) && defined(CONFIG_COMPAT) > /* > diff --git a/fs/f2fs/file.c b/fs/f2fs/file.c > index b3985a6..6d3cfd5 100644 > --- a/fs/f2fs/file.c > +++ b/fs/f2fs/file.c > @@ -1498,6 +1498,10 @@ static int f2fs_ioc_shutdown(struct file *filp, unsigned long arg) > case F2FS_GOING_DOWN_NOSYNC: > f2fs_stop_checkpoint(sbi); > break; > + case F2FS_GOING_DOWN_METAFLUSH: > + sync_meta_pages(sbi, META, LONG_MAX); > + f2fs_stop_checkpoint(sbi); > + break; > default: > return -EINVAL; > } > -- > 2.1.1 > > > ------------------------------------------------------------------------------ > _______________________________________________ > Linux-f2fs-devel mailing list > Linux-f2fs-devel@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/linux-f2fs-devel -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

This patch introduces F2FS_GOING_DOWN_METAFLUSH which flushes meta pages like SSA blocks and then blocks all the writes. This can be used by power-failure tests. Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org> --- fs/f2fs/f2fs.h | 1 + fs/f2fs/file.c | 4 ++++ 2 files changed, 5 insertions(+)
