FMODE_EXEC is type fmode_t but is used in operations
with integers which leads to sparse warnings:
drivers/staging/lustre/lustre/mdc/mdc_lib.c:198:21: warning: restricted fmode_t degrades to integer
drivers/staging/lustre/lustre/mdc/mdc_locks.c:300:49: warning: restricted fmode_t degrades to integer
Fix by using __FMODE_EXEC macro defined in fs.h.
Note the same warnings occurs with other fmode flags
here but they don't have a corresponding int macro.
Changes since v1:
remove ifdefs. FMODE_EXEC and __FMODE_EXEC should
always be defined in fs.h

ksock_net_t uses a __u64 quantity as an 'incarnation' timestamp. This is also
passed on in hello messages and used to detect if a reboot has occurred.
This 'incarnation' is obtained using do_gettimeofday.It is only used in equality
checks, so the absolute value does not matter.
This patch replaces do_gettimeofday with ktime_get_ns for the following reasons:
1. ktime_get_ns returns a __u64 which is safer than 'struct timeval'
which will overflow on 32-bit systems in year 2038 and beyond.
2. Reduced compute: ktime_get_ns is faster than the multiply/add
combination used in this function

If size is smaller than the lov_user_md struct then we are reading

This is mostly to silence static checker complaints.
In theory the problem here is that if size is in the 1-3 range then we
don't allocate enough memory for the posix_acl_xattr_header struct and
it results in memory corruption. But in reality kmalloc() return values
are aligned at sizeof(long) so corrupting this small amount of data is
not harmful.
The "size" variable should be type size_t. The value of size is checked
in setxattr() so we know it is a number between "0 - XATTR_SIZE_MAX".
There is no need to check for negative sizes.
