Subject: [PATCH] v9fs: allocate the Rwalk qid array from the right conv buffer
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=5b067676234715051cbde87083c36c8ea83f77b8;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

[PATCH] v9fs: allocate the Rwalk qid array from the right conv buffer

When v9fs_deserealize_fcall deserializes a Rwalk message, it incorrectly
allocates space for the qid array in the source instead of the destination
buffer.
