posix: Ignore disk space reserve check for internal FOPS
Problem: Currently disk space reserve check is applicable for internal FOP also it needs to be ignore for internal FOP. Solution: Update the DISK_SPACE_CHECK_AND_GOTO macro at posix component. Macro will call only while key "GLUSTERFS_INTERNAL_FOP_KEY" exists in xdata. BUG: 1506083 Change-Id: I2b0840bbf4fa14bc247855b024ca136773d68d16 Signed-off-by: Mohit Agrawal <moagrawa@redhat.com>
