Hi,

[ drop kernel developers, add Jan, Li ]

@Jan, you added in 9120d8a22 ("safe_macros: turn functions with off_t parameter
into static inline") note "following functions are inline because the behaviour
may depend on -D_FILE_OFFSET_BITS=64 -DOFF_T=__off64_t compile flags". IMHO the
only source which uses SAFE_MMAP() is testcases/kernel/mem/mmapstress/mmapstress01.c
I'm asking because I wonder if SAFE_MPROTECT() and SAFE_MREMAP() should be also
static inline, IMHO it's not needed.

@all: SAFE_MPROTECT() would be needed also on some still old API sources
(testcases/kernel/syscalls/signal/signal06.c,
testcases/kernel/syscalls/mprotect/mprotect02.c,
testcases/kernel/syscalls/mprotect/mprotect03.c)
Should I ignore that and add it just to new API?

Kind regards,
Petr
