[PATCH] dm: clear BIO_SEG_VALID in clone_bio

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Since 57c36519e4("dm: fix clone_bio() to trigger blk_recount_segments()")
has been reverted by fa8db494("dm: don't use bio_trim() afterall"), the
problem that clone bio won't trigger blk_recount_segments will exits
again. So just clean the flag in clone_bio.

Fixes: fa8db4948f522("dm: don't use bio_trim() afterall")
