From: Oleg Drokin Date: Fri, 24 Jan 2014 04:45:06 +0000 (-0500) Subject: lustre: Account for changelog_ext_rec in CR_MAXSIZE X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=910827f17496e03d23577c580e2456604caa9f35;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git lustre: Account for changelog_ext_rec in CR_MAXSIZE CR_MAXSIZE needs to account for an llog_changelog_rec that actually contains a changelog_ext_rec structure rather than a changelog_rec. With out doing so, a file size approaching the Linux kernel NAME_MAX length that is renamed to a size also close to, or at, NAME_MAX will exceed CR_MAXSIZE and trip an assertion.
