Wong" Cc: linux-fsdevel , linux-mm , LKML , Jens Axboe , Jan Kara Hi Darrick, can you tell me why you do not put your help text where it normally belongs ("help" Kconfig item)? 273 # We also use the bounce pool to provide stable page writes for jbd. jbd 274 # initiates buffer writeback without locking the page or setting PG_writeback, 275 # and fixing that behavior (a second time; jbd2 doesn't have this problem) is 276 # a major rework effort. Instead, use the bounce buffer to snapshot pages 277 # (until jbd goes away). The only jbd user is ext3. 278 config NEED_BOUNCE_POOL 279 bool 280 default y if (TILE && USB_OHCI_HCD) || (BLK_DEV_INTEGRITY && JBD) 281 help 282 line #273..277 Noticed while hunting a culprit commit in Linux-Next as my kernel-config got changed between next-20130123..next-20130124.
