Subject: Re: block: optionally snapshot page contents to provide stable pages during write
Date: Sat, 26 Jan 2013 13:39:46 +0100 [thread overview]
Message-ID: <CA+icZUXsi0jZZE9HBWG0D6-+oJBeX+8nHpZ9F02x=B7dG3X+yg@mail.gmail.com> (raw)
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.
