Re: [PATCH] Declare the file_operations struct as const

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



I unfortunately forgot to add Greg to this thread. Doing so now. I
apologize for the confusion, if any. This patch was regarding the
staging tree's file android/ashmem.c and declaring the file_operations
struct as const as done elsewhere in the kernel, because there are no
modifications to its fields.

Warm Regards
