Subject: [PATCH] sysfs: fix sysfs_setattr
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9ca1eb3282b6050c295adb296761f8d26baf4ca5;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

[PATCH] sysfs: fix sysfs_setattr

o sysfs_dirent's s_mode field should also be updated in sysfs_setattr(), else
  there could be inconsistency in the two fields. s_mode is used while
  ->readdir so as not to bring in the inode to cache.
