From: Ram Gupta Date: Thu, 25 Oct 2007 15:03:28 +0000 (-0500) Subject: fs: Fix to correct the mbcache entries counter X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f9e83489cbb3670df810d4f9fe308cde88faa0a9;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git fs: Fix to correct the mbcache entries counter This patch fixes the c_entry_count counter of the mbcache. Currently it increments the counter first & allocate the cache entry later. In case of failure to allocate the entry due to insufficient memory this counter is still left incremented. This patch fixes this anomaly.
