Subject: [RFC PATCH V11 20/21] Btrfs: subpagesize-blockssize: Limit inline extents to root->sectorsize.
Date: Mon, 1 Jun 2015 20:52:55 +0530 [thread overview]
Message-ID: <1433172176-8742-21-git-send-email-chandan@linux.vnet.ibm.com> (raw)
In-Reply-To: <1433172176-8742-1-git-send-email-chandan@linux.vnet.ibm.com>
cow_file_range_inline() limits the size of an inline extent to
PAGE_CACHE_SIZE. This breaks in subpagesize-blocksize scenarios. Fix this by
comparing against root->sectorsize.
